Getting pregnant involves more than stopping birth control and hoping for the best. A few targeted steps, from timing sex to adjusting everyday habits, can meaningfully improve your chances each cycle. Here’s what actually matters when you’re ready to start trying.
Stop Birth Control and Know What to Expect
How quickly fertility returns depends on what type of contraception you’ve been using. IUD users (both hormonal and copper) and implant users see the shortest delay, averaging about two cycles. If you’ve been on the pill or a vaginal ring, expect roughly three cycles before your body’s normal fertility resumes. Patch users average about four cycles.
The longest wait comes after injectable contraceptives like the shot, which suppress ovulation more deeply. Fertility typically returns within five to eight cycles, so if you’re on the shot and want to conceive soon, switching to a shorter-acting method in advance can save you months of waiting.
During this transition, your periods may be irregular for a few cycles. That’s normal and doesn’t mean something is wrong. Tracking your cycle from the start gives you useful data even before things regulate.
Start Folic Acid Before You Conceive
Every woman planning a pregnancy should take 400 micrograms of folic acid daily, starting at least one month before conception. This B vitamin dramatically reduces the risk of neural tube defects, which affect the brain and spinal cord very early in pregnancy, often before you even know you’re pregnant. The CDC recommends all women capable of becoming pregnant take this amount every day, since about half of pregnancies are unplanned.
Most prenatal vitamins contain the right dose. If you haven’t started one yet, picking up a prenatal vitamin is the single easiest step you can take right now.
Learn Your Fertile Window
There are only about six days per menstrual cycle when pregnancy is possible. This fertile window includes the five days before ovulation and the day of ovulation itself. You’re most likely to conceive if you have sex in the few days leading up to ovulation, because sperm can survive in the reproductive tract for several days while an egg lives only 12 to 24 hours after release.
For women with a regular 28-day cycle, ovulation typically happens around day 14. But cycles vary, and ovulation can shift from month to month. That’s where tracking comes in.
How to Track Ovulation
Cervical mucus is one of the most reliable free indicators of fertility. Throughout your cycle, the texture and appearance of your cervical mucus changes. The most fertile type is transparent, stretchy, and slippery, similar to raw egg white. When you notice this mucus, ovulation is likely close. Research from UNC School of Medicine found that the best chance of pregnancy occurs when intercourse happens on a day near ovulation while this type of mucus is present.
Ovulation predictor kits (available at any pharmacy) detect a hormone surge that happens one to two days before you ovulate. Basal body temperature tracking can confirm that ovulation occurred, though it’s less useful for predicting it in real time since the temperature rise happens after the egg is already released. Many people combine two or three methods for the clearest picture.
How Often to Have Sex
During your fertile window, having sex every day or every other day gives you the best chance. The American College of Obstetricians and Gynecologists is clear that you don’t need to have sex every single day for it to work. Every other day during those six fertile days is just as effective for most couples.
Outside the fertile window, frequency doesn’t matter much for conception purposes. The bigger risk is turning sex into a chore. If tracking and scheduling starts to feel stressful, having sex two to three times per week throughout the month covers your bases without the pressure of perfect timing.
Weight and Fertility
Body weight has a direct effect on ovulation. Fat cells produce estrogen, and when you carry excess weight, the extra estrogen can trick your body into behaving as though you’re already on hormonal birth control or pregnant. This can prevent ovulation entirely and cause irregular or absent periods. A BMI of 30 or higher falls into the obesity range and carries the highest risk of ovulation disruption.
Being underweight (a BMI below 18.5) creates the opposite problem. Too little body fat means too little estrogen, which can also shut down ovulation and stop your period. The optimal range for fertility is a BMI between 18.5 and 24.9. Even modest weight changes in either direction, gaining five to ten pounds if you’re underweight or losing five to ten percent of body weight if you’re overweight, can restore regular ovulation for many women.
What Your Partner Can Do
Sperm quality matters just as much as egg quality, and several lifestyle factors have a proven impact. Smoking lowers sperm count. Heavy drinking reduces both sperm count and testosterone. Carrying excess weight is linked to lower sperm count and reduced sperm movement.
Heat is a surprisingly significant factor. The testicles hang outside the body for a reason: sperm production requires a cooler temperature. Frequent sauna or hot tub use, prolonged sitting (especially with a laptop on the lap), and tight underwear can all raise scrotal temperature enough to impair sperm production. Switching to loose-fitting boxers, taking breaks from sitting, and avoiding hot tubs during the months you’re trying to conceive are simple changes that can help.
Reduce Chemical Exposures
Certain everyday chemicals act as endocrine disruptors, meaning they interfere with the hormones that regulate fertility and fetal development. BPA and its replacement BPF, found in plastic food containers, water bottles, receipt paper, and some varnishes, are among the most studied. Reducing your exposure is straightforward: use glass or stainless steel containers for food and drinks, avoid microwaving plastic, and wash your hands after handling receipts.
Pesticide residues on produce are another source of exposure. Washing fruits and vegetables thoroughly or choosing organic versions of the most heavily sprayed crops can help. If your home was built before the late 1970s, lead in old paint or plumbing is worth checking on, since lead exposure is harmful during pregnancy. Both partners should also avoid cigarette and vape smoke, which contain chemicals like benzene and nickel that affect reproductive health.
Understand the Role of Age
Age is the single biggest factor in how quickly you’ll conceive. A woman in her early to mid-20s has a 25 to 30 percent chance of getting pregnant in any given cycle. That’s the peak. Fertility declines gradually through the 30s and more steeply after 35. By age 40, the chance of conceiving in any one cycle drops to around 5 percent.
These numbers don’t mean pregnancy at 35 or 40 is unlikely. They mean it typically takes more cycles. A 25-year-old with a 25 percent monthly chance will likely conceive within four to five months. A 40-year-old with a 5 percent monthly chance may need a year or more. Knowing this helps set realistic expectations and informs how long to try before seeking help.
How Long to Try Before Seeking Help
If you’re under 35, the standard guideline is to try for 12 months of well-timed intercourse before pursuing a fertility evaluation. If you’re 35 or older, that timeline shortens to six months. Women over 40 may benefit from earlier evaluation, since the window for intervention is narrower.
These timelines assume nothing else is going on. If you have a known condition that affects fertility, such as endometriosis, polycystic ovary syndrome, very irregular periods, or a history of pelvic infections, there’s no reason to wait. The same applies if your partner has a known issue like undescended testicles or a prior cancer treatment. In those cases, connecting with a reproductive specialist right away makes sense.
