Can You Have an Abortion at 20 Weeks?

In many parts of the world, abortion at 20 weeks of pregnancy is legally permitted and medically performed, though access varies enormously depending on where you live, who your provider is, and why you need the procedure. Twenty weeks sits at a medically significant crossroads: it is roughly the point at which the standard anatomy scan takes place, meaning some serious fetal diagnoses are only just being discovered. It is also the gestational age at which legal restrictions begin to tighten in many jurisdictions, and the point at which the procedure itself becomes more complex. The answer to whether you can have an abortion at 20 weeks is technically yes in many circumstances, but the practical reality is far more complicated than the technical answer.

Why 20 Weeks Is a Turning Point

Professional medical societies recommend the second-trimester anatomy scan between 18 and 22 weeks as the gold standard for detecting fetal anomalies.¹ That scan is often the first time a pregnant person learns about a serious structural or chromosomal abnormality. Some conditions, like certain heart defects or brain malformations, simply cannot be seen on earlier ultrasounds because the relevant anatomy has not developed enough to evaluate. One study tracking detection rates found that by week 17, about 72% of anomalies that would eventually be found were detectable, compared to 55% at week 14.² That still leaves a substantial share of diagnoses that emerge only at or after the 18-to-22-week window.

This timing creates an inherent tension. A person who receives devastating news at their 20-week scan faces an immediate decision about whether to continue the pregnancy, but by the time they process the diagnosis, get a second opinion, and arrange care, they may already be pushing against gestational limits in their jurisdiction. The medical calendar and the legal calendar do not always align, and people seeking abortions at this stage are frequently doing so because of information they literally could not have had any earlier.

Who Seeks Abortion at 20 Weeks and Why

The popular image of a person seeking a later abortion as someone who simply “waited too long” does not hold up to scrutiny. Research consistently identifies two broad groups: people who learned something new about the pregnancy that changed their decision, and people who wanted an earlier abortion but could not get one in time.³

In the first group, fetal anomalies are a major driver. The most common anomalies found in mid-trimester scans include clubfoot, ventriculomegaly (excess fluid in the brain), digital abnormalities, hydronephrosis (swelling in the kidneys), and heart defects.² Some of these are manageable after birth; others are incompatible with life or predict severe disability. Maternal health conditions also drive later terminations. Cardiac disease, kidney problems, autoimmune disorders, and psychiatric conditions are among the recognized maternal indications for pregnancy termination.⁴ A pregnancy that was safe at 10 weeks can become dangerous by 20 weeks as the cardiovascular and metabolic demands increase.

In the second group, the delays are often logistical, not decisional. One study found that roughly half of the total delay between first- and second-trimester abortions was caused by later suspicion of pregnancy and later testing. Nearly 60% of people who ended up needing a second-trimester procedure had missed the first-trimester window for reasons beyond their control.⁵ People presenting for second-trimester care experienced an average of 3.2 delaying factors, compared to 2.0 for first-trimester patients, and logistical delays like difficulty finding a provider or getting insurance approval were far more common among the later group.

Another study found that about 59% of people cited how long it took to arrange the procedure as a reason for delay, while 39% cited the difficulty of the decision itself and 36% said they found out about the pregnancy late. People with lower incomes were roughly twice as likely to be delayed by logistical problems.⁶

How the Procedure Works at 20 Weeks

At 20 weeks, there are two main approaches: dilation and evacuation (D&E) and induction of labor. D&E is a surgical procedure and is the more common method in settings where trained providers are available. Induction of labor uses medication to cause contractions, essentially a miniature labor and delivery.

D&E requires the cervix to be dilated sufficiently to allow instruments to pass safely. Providers typically prepare the cervix beforehand using osmotic dilators, which are thin rods inserted into the cervix that absorb moisture and gradually expand, or medications like misoprostol and mifepristone, or a combination.⁷ This preparation reduces the risk of injury to the cervix and uterus.⁸ The preparation stage may take hours to overnight, and the procedure itself is then performed under sedation or anesthesia.

Clinically recognized infection rates during second-trimester abortion are low regardless of which type of dilator is used.⁹ When pregnancies are being terminated because of detected fetal abnormalities, D&E has been described as the “procedure of choice” in the second trimester, with one case series of 60 consecutive patients confirming that prenatal diagnoses were accurately verified in every case.¹⁰

D&E Compared to Induction of Labor

The choice between D&E and induction matters, and the evidence generally favors D&E for safety in the second trimester. One comparative study found that adverse events were more than three times as common with induction of labor compared to D&E (about 52% versus 17%), and induction was an independent risk factor for complications, with roughly a sixfold increase in odds. Severe complications were rare with either method.¹¹ Another study found that overall complication rates were somewhat higher with induction (about 10%) compared to D&E (about 6%), driven mainly by minor complications.¹²

Induction does have one advantage: it is much more likely to yield a specimen suitable for a full autopsy, which can be important when a family wants a definitive diagnosis of a fetal condition. The same study found that about 94% of induction patients had a successful autopsy, compared to about 35% in the D&E group, though the ability to obtain genetic analysis was similar between the two methods (roughly 89-92%).¹² For families grappling with a rare diagnosis, this can be a meaningful factor in deciding which procedure to pursue.

In practice, many patients at 20 weeks do not get to choose. Access to D&E depends heavily on whether a trained provider is available, and many hospitals and clinics do not offer it. Barriers to second-trimester abortion training include lack of leadership at training programs, difficulty obtaining necessary medications, and institutional resistance from personnel who object to the procedure.¹³ When D&E is not available, induction may be the only option, or the patient may need to travel to another facility entirely.

Safety for Future Pregnancies

A common worry for people considering a 20-week abortion is whether it will affect their ability to have children in the future. The evidence on this is reassuring. Research has found that second-trimester D&E does not increase the risk of midtrimester pregnancy loss or spontaneous preterm birth in subsequent pregnancies. In fact, greater preoperative cervical dilation with laminaria appeared to decrease future preterm delivery, likely because it reduced cervical trauma during the procedure.¹⁴

A more recent study compared outcomes for pregnancies conceived after second-trimester uterine evacuation versus after first-trimester procedures and found no additional risk for preterm delivery or other adverse outcomes in the second-trimester group.¹⁵ These findings should be genuinely comforting to anyone agonizing over this question, though individual risk can vary based on the specifics of the procedure and the provider’s experience.

The Legal Landscape

Where you can actually access a 20-week abortion depends heavily on where you live. In the United States, the legal picture has fragmented dramatically since the Supreme Court’s 2022 Dobbs decision. Some states ban abortion outright or at six weeks, well before most people even know they are pregnant. Others permit abortion up to viability or beyond, with varying definitions of what that means. A handful of states have no gestational limit at all. This patchwork means that a 20-week abortion may be straightforward to obtain in one state and completely illegal in the neighboring one.

In Europe, similar variation exists. Many countries set gestational limits for elective abortion between 10 and 14 weeks, with exceptions for fetal anomaly or maternal health that extend to later gestational ages. A study of people who crossed borders for abortion care in Europe found that patients arrived at a median of 18 weeks, and about 79% cited their home country’s gestational limit as the primary reason for traveling.¹⁶ The UK and the Netherlands were common destinations. These are people who needed later care and could not get it at home, forced to navigate international travel while pregnant and under time pressure.

The concept of fetal viability itself has been shifting as neonatal intensive care has improved. What was considered non-viable at 24 weeks a few decades ago has gradually moved earlier, though survival rates below 23-24 weeks remain very low and outcomes for survivors are often serious.¹⁷ The legal frameworks that tie abortion access to viability are therefore built on a moving target, and this creates confusion for both providers and patients about what is permitted.

Access Barriers and Distance

Even where 20-week abortion is legal, actually getting one can be extraordinarily difficult. People seeking abortions at 16 weeks or later are twice as likely to travel more than 100 miles compared to those at 12 weeks or earlier. Those who cross state lines are eight times more likely to travel long distances than those who stay in-state.¹⁸ People living in rural areas face the same eightfold increase in travel distance compared to those in metropolitan areas.

Cost compounds the access problem. When insurance or Medicaid covers an abortion, out-of-pocket costs can be minimal or zero. When they do not, the median cost rises to several hundred dollars, and for later procedures the costs are considerably higher. For more than half of patients paying out of pocket, the expense amounted to more than a third of their monthly personal income, rising closer to two-thirds for those getting later abortions. More than half of those patients said cost was a reason they delayed the procedure, creating a vicious cycle where financial barriers push the procedure later, which makes it more expensive and harder to access.¹⁹

The Fetal Pain Question

Debates over 20-week abortion often center on fetal pain, and this is an area where public perception significantly outpaces the science. A comprehensive review of the evidence found that fetal perception of pain is unlikely before the third trimester. The neural pathways required for conscious pain experience, the connections between the thalamus and the cortex, do not begin to function until around 29 to 30 weeks. Reflexive withdrawal movements that occur earlier in development are not evidence of pain perception; they are automatic spinal responses that do not involve the brain’s cortex and are not specific to painful stimuli.²⁰

This finding is directly relevant to the policy debate. Several U.S. states have passed or attempted to pass 20-week abortion bans based on the claim that fetuses can feel pain at that stage. The available evidence does not support that claim. The hormonal stress responses that are sometimes cited as proof of pain are present from early in development and are not cortically mediated, meaning they occur without conscious experience, in the same way your knee jerks when tapped without you feeling pain from the reflex itself.

Emotional and Psychological Impact

Ending a pregnancy at 20 weeks is emotionally difficult for most people, regardless of the circumstances. For those terminating a wanted pregnancy because of fetal anomalies, the grief can be intense. A pilot study comparing psychological outcomes after first- and second-trimester terminations for fetal anomaly found high levels of distress in both groups, but those who had second-trimester procedures showed significantly higher levels of post-traumatic stress symptoms six weeks afterward.²¹

A larger longitudinal study found that about four months after a second-trimester termination, roughly 27% of women and 9% of men showed signs of pathological grief. About one in five women screened positive for postnatal depression. Having a prior psychiatric history was a strong predictor of worse outcomes. One unexpected finding: donating fetal tissue to a biobank was associated with reduced complicated grief, suggesting that a sense of meaning or contribution may help some people process the experience.²²

Partners are often overlooked in this research and in clinical care. The same study found that men also experience significant grief, albeit at lower rates. Providing support and follow-up for both partners, not just the pregnant person, seems warranted given these numbers.

When a 20-Week Abortion Becomes a 22- or 24-Week Abortion

One of the least discussed aspects of this topic is what happens when someone who needs an abortion at 20 weeks cannot get one at 20 weeks. Every delay pushes the procedure later, the medical complexity increases, the number of willing providers shrinks, the cost goes up, and the legal window may close. The logistical barriers documented in the research, including difficulty finding a provider, getting a referral, arranging transportation, and securing funding, do not resolve themselves. They compound. A person who needs the procedure at 20 weeks but faces a two-week delay getting an appointment is now at 22 weeks, where fewer clinics operate and some state laws have kicked in. Another week of delay to arrange travel and lodging brings them to 23 weeks, where options narrow further.

The European data makes this dynamic visible in cross-border terms. When patients arrived at clinics in the UK or the Netherlands for care they could not access at home, the median gestational age was already 18 weeks.¹⁶ By the time travel was arranged, consultations completed, and the procedure scheduled, many were past 20 weeks. In the U.S., prior second-trimester abortion was itself a risk factor for needing another second-trimester procedure, suggesting that the same structural barriers that caused delay the first time tend to persist.⁵ The system that makes 20-week abortion hard to get is the same system that creates the need for 22- and 24-week abortions.

What Providers Face

The shortage of providers willing and trained to perform D&E at 20 weeks is itself a barrier that rarely gets public attention. Training programs for second-trimester procedures face specific obstacles: turnover in program leadership, institutional conflicts, difficulty stocking mifepristone, and the fact that training is often optional rather than a standard part of obstetric residency. Personnel at some hospitals hold personal objections to abortion that create a hostile environment for trainees.¹³ The result is that each year, fewer new physicians enter practice with the skills to offer this care, even as the clinical need persists.

For providers who do offer second-trimester procedures, the work carries professional and personal costs. Clinic security concerns, stigma from colleagues, and the emotional weight of the work contribute to burnout. In regions where clinics have closed, the remaining providers absorb higher patient volumes and more complex cases, often traveling across state lines themselves to deliver care. The concentration of later abortion services into fewer and fewer hands makes the entire system fragile. If a single provider in a region retires or stops practicing, patients in that area may lose access entirely.
