How Long Does It Take to Get Pregnant After Birth Control?

Most people who stop using birth control can expect to conceive within about a year, regardless of the method they were on. A large systematic review and meta-analysis found a pooled pregnancy rate of roughly 83% within the first twelve months after discontinuing contraception, with no significant difference between hormonal methods and IUDs.¹ That said, the specific method you were using matters more than most people realize, and one method in particular stands out as a slow outlier.

The Pill

Combined oral contraceptives are the method most people picture when they ask about fertility after birth control, and they carry the most anxiety. The short version: there is a real but temporary dip in fertility during the first several months after stopping the pill, but it fades. One early and frequently cited study in the BMJ found that fertility was initially lower in women who had stopped oral contraceptives compared with those who had stopped other methods, but the effect had become negligible by about 30 months in women who had previously given birth and by 42 months in women who had not.² Those numbers sound alarming, but they describe the tail end of the curve. The vast majority of former pill users conceive well before that window closes.

A later review pulling together data from numerous studies reported that twelve-month conception rates among former pill users ranged from about 72% to 94%, which is roughly comparable to the rates seen after stopping IUDs, progestin-only methods, condoms, and natural family planning.³ In practical terms, if you stop taking the pill and start trying, your chances of being pregnant within a year are similar to those of someone who was never on hormonal birth control at all. The initial delay shows up most clearly in the first one to three cycles, when your body is re-establishing its own hormonal rhythm, and for most people it resolves quickly.

IUDs, Both Hormonal and Copper

IUDs have a reputation for fast fertility return, and the evidence backs that up for both types. A study comparing the hormonal levonorgestrel IUD (the kind that releases a small amount of progestin) with the copper Nova-T found that about 79% of women in the hormonal IUD group had conceived within 12 months of removal, and roughly 87% by 24 months. Those rates were not significantly different from the copper IUD group, and in both groups about 96% of the pregnancies occurred during the first year.⁴ The researchers noted that despite the hormonal IUD’s suppression of the uterine lining during use, the endometrium recovers quickly once the device comes out.

A separate long-term study of copper IUD users found that about 64% conceived within six months of removal and roughly 84% within one year.⁵ By two years, that climbed to about 95%. These numbers reinforce what clinicians generally tell patients: the IUD, whether hormonal or copper, is among the most “reversible” forms of long-acting contraception. Once it is removed, there is essentially no lingering contraceptive effect to wait out.

The Implant

Contraceptive implants like Nexplanon release a steady dose of a progestin called etonogestrel, and they suppress ovulation very effectively for up to three years. There is less large-scale data specifically tracking time-to-pregnancy after implant removal compared with the pill or IUDs, partly because implant users represent a smaller share of the contraceptive market. The large post-marketing NORA study, which followed over 7,300 Nexplanon users, recorded 14 pregnancies after implant removal, all of which occurred in women who were trying to conceive, and 22 of the 26 total pregnancies across the study resulted in the birth of a healthy child.⁶ The study was not designed to measure time-to-pregnancy specifically, but the broader meta-analytic data suggests implant users fall within the same general twelve-month fertility return window as other hormonal method users.¹

Clinically, ovulation can return within weeks of implant removal, since the body is no longer receiving the progestin that was suppressing it. Many people report getting a period within a month or so of removal, though the first few cycles may be irregular as the hypothalamic-pituitary-ovarian axis recalibrates.

The Shot Is the Outlier

If there is one method that genuinely delays fertility return in a way you should plan around, it is injectable depot medroxyprogesterone acetate, commonly known as the Depo-Provera shot. Research going back decades consistently shows a longer wait. One study found that the median delay before conception was about 5.5 months after the estimated duration of the last injection wore off. Since each shot is designed to last roughly 15 weeks, that puts the median total delay at about nine months from the last injection.⁷

A separate review confirmed this pattern, estimating a prolongation of about eight months compared with other methods, but stressed that eventual pregnancy rates are not lower; the curve just shifts to the right.⁸ Importantly, the delay does not grow with the number of injections you have received. Someone who was on the shot for five years does not face a longer wait than someone who was on it for one year. The body simply needs time to clear the depot of hormone that was injected into the muscle, and that clearance timeline is relatively fixed.

If you are on the shot and thinking about trying to conceive in the near future, switching to a shorter-acting method a few months before you want to start trying is a common strategy clinicians suggest. That way, the long washout period from the final injection can overlap with the time you are still on another method, rather than adding months to your timeline.

Does How Long You Were on Birth Control Matter?

This is one of the most persistent worries: that years and years on hormonal contraception somehow build up and delay fertility proportionally. The evidence says otherwise. The same systematic review that reported the 83% twelve-month pregnancy rate also found that duration of oral contraceptive use did not significantly influence the return of fertility.¹ The early BMJ study reached the same conclusion, finding that impairment appeared to be independent of the length of use of oral contraceptives.²

Perhaps the most counterintuitive finding comes from a study published in Human Reproduction, which found that prolonged use of oral contraception was actually associated with a decreased risk of delayed conception. The researchers controlled for other factors, including whether the women had been pregnant before, and still found the association held. Their conclusion was that women who have used oral contraceptives for a long time can be reassured that they will not be disadvantaged in terms of time taken to conceive.⁹ The probable explanation is not that the pill improves fertility. Rather, hormonal contraception suppresses conditions like endometriosis and ovarian cysts that can worsen over time, so long-term users may arrive at the “trying to conceive” stage with less accumulated reproductive damage than they would have had without contraception.

Tracking Ovulation to Shorten the Wait

One of the most straightforward things you can do once you stop birth control is pay attention to when you are ovulating. A review of ovulation and luteal phase tracking technologies noted that mistiming intercourse is one of the primary causes of apparent infertility, and that tracking ovulation has been shown to decrease the average time to conception.¹⁰ This matters especially in the first few months after stopping hormonal contraception, when your cycle length may be unpredictable and ovulation may shift from month to month.

Most over-the-counter ovulation predictor kits detect a surge in luteinizing hormone in your urine, which typically precedes ovulation by about a day or two. That can help you identify the fertile window. However, the same review pointed out that most available apps and kits are predictive tools that do not actually confirm whether ovulation has occurred or assess the health of the luteal phase (the second half of your cycle, after ovulation). If you have been off birth control for several months and your cycles remain very irregular or you are not seeing signs of ovulation, that information is worth bringing to a clinician sooner rather than later.

One practical note: do not assume your pre-birth-control cycle length will return immediately. Hormonal contraception overrides your natural cycle, so the “28-day cycle” you experienced on the pill was pharmaceutically imposed. Your natural cycle length may be shorter or longer, and it can take a few months to settle into a consistent pattern.

Emergency Contraception and Future Fertility

A related concern that comes up frequently is whether using emergency contraception, particularly the levonorgestrel “morning-after pill,” affects future fertility. A review examining the effects of levonorgestrel emergency contraception found no evidence of increased miscarriage, birth defects, or disrupted menstrual cycles after exposure compared with controls.¹¹ Emergency contraception works primarily by delaying or preventing ovulation in that particular cycle. It does not create any lasting change to your reproductive system, and there is no cumulative harm from using it more than once, despite what some popular sources suggest.

Tubal Sterilization Reversal

Sterilization is a very different situation from reversible birth control, and people considering reversal face a genuinely different fertility landscape. A population-based study of women who underwent tubal sterilization reversal found that the cumulative live-delivery rate was about 20% within the first year after reversal, 40% at two years, and 51% at five years.¹² Those rates are substantially lower than the twelve-month conception rates seen with reversible methods, and they depend heavily on factors like age at the time of reversal, the original sterilization technique, and how much healthy fallopian tube remains.

For context, the roughly 50% five-year success rate after tubal reversal is why many reproductive endocrinologists steer patients toward IVF instead, especially if the patient is over 35 or if the original procedure removed a large portion of the tube. Both paths are expensive, and neither is guaranteed. The key distinction is that tubal sterilization is designed to be permanent and, unlike every other method discussed here, the “reversal” is a surgical reconstruction with meaningfully lower fertility odds.

When the Wait Feels Longer Than It Should

It is worth separating the effect of birth control from the effect of age. Many people start contraception in their late teens or twenties and stop it in their thirties, and the fertility decline that happens naturally over that decade can be mistakenly attributed to the contraception itself. A person who started the pill at 22 and stopped at 34 is not experiencing delayed fertility because of twelve years on the pill; they are experiencing the normal fertility curve of a 34-year-old. The evidence on duration of use, as discussed above, confirms that the pill is not adding to that decline.

The standard clinical guideline is to seek evaluation after twelve months of unprotected intercourse without pregnancy if you are under 35, or after six months if you are 35 or older. Those timelines apply regardless of whether you were recently on birth control. The one exception worth flagging is the Depo-Provera shot: if you stopped the shot and are still not ovulating after twelve months, that is worth investigating, though even then the usual cause is simply a slower-than-average hormone clearance rather than a permanent change.

Underlying conditions like polycystic ovary syndrome, endometriosis, or thyroid disorders can also affect time to pregnancy, and these conditions may have been masked by hormonal contraception. The pill, for example, regulates your cycle and suppresses many PCOS symptoms. Once you stop, those symptoms reemerge, and it can feel like the pill caused the problem when it was actually managing it. If you had irregular or absent periods before starting birth control, be prepared for that pattern to return and discuss it with your provider early in the process rather than waiting a full year.

The Myth of “Detoxing” from Birth Control

A growing corner of wellness culture promotes “birth control detoxes,” supplement regimens, or extended waiting periods before trying to conceive, based on the idea that synthetic hormones leave behind residues that need to be flushed out. There is no scientific support for this. Synthetic hormones from the pill, patch, and ring are metabolized and cleared within days of your last dose. The implant and IUD stop delivering hormones the moment they are removed. Even the Depo-Provera shot, which has the longest pharmacological tail, works by slowly releasing hormone from a depot in the muscle; once the depot is depleted, there is nothing left to “detox.”

The idea that you should wait several cycles “to let your body recover” before trying to conceive is also unsupported. There is no increased risk of miscarriage or birth defects associated with conceiving in the first cycle after stopping hormonal contraception. The reason a healthcare provider might suggest waiting for one natural period before trying is practical, not medical: having a known last menstrual period makes it easier to date a pregnancy accurately. If you happen to conceive before that first natural period arrives, the pregnancy is not at higher risk; your provider will simply use an early ultrasound for dating instead.

Supplements marketed specifically as birth control detoxification products typically contain standard vitamins and minerals, such as folate, B vitamins, and magnesium, which are reasonable to take while trying to conceive. But the framing that you need them to undo hormonal damage is misleading. Taking a prenatal vitamin is a good idea for anyone planning a pregnancy. Buying a product labeled as a “post-pill cleanse” is paying extra for the same ingredients wrapped in unfounded anxiety.
