Does Birth Control Make It Harder to Get Pregnant?

Birth control does not make it harder to get pregnant in the long run. Regardless of the type of hormonal contraception you use or how many years you stay on it, your fertility returns to its baseline level after you stop. There can be a short delay of a few months before your cycles fully normalize, but this is temporary and does not affect your overall chances of conceiving.

What the Research Actually Shows

A systematic review published in Contraception and Reproductive Medicine looked across studies and found that the type of contraception, the type of hormone in it, and the duration of use do not significantly influence the return of fertility after stopping. Women who used birth control for a decade had the same pregnancy outcomes as women who used it for a year or two. The slight dip in pregnancy rates sometimes seen among long-term users appears to be explained by age: fertility naturally declines as you get older, and that decline happens whether you’re on birth control or not.

The researchers concluded that prior contraceptive use, regardless of duration and type, does not have a negative effect on subsequent fertility. That’s a strong, reassuring finding backed by pooled data from multiple studies.

The First Few Months May Be Different

While birth control doesn’t cause lasting harm to fertility, your body does need a brief adjustment period after stopping. Research from the Journal of Women’s Health found that women who recently discontinued oral contraceptives had longer menstrual cycles and measurable differences in ovulation timing compared to women who hadn’t been on the pill. These differences trended toward normal over the first six cycles, with most biomarkers stabilizing within about nine months.

This means your chances of conceiving in the very first month or two off the pill may be slightly lower than someone who hasn’t been using hormonal birth control. But that gap closes quickly. By the time you’ve had a few regular cycles, your fertility is back to where it would have been without contraception.

A small number of women experience what’s called post-pill amenorrhea, where their period doesn’t return for up to six months after stopping oral contraceptives. This typically resolves on its own and only requires medical attention if you’re actively trying to conceive.

How Timelines Differ by Method

Not all methods wear off at the same speed. The pill, patch, and ring tend to clear your system relatively quickly, with a median delay to conception of about three months after the last dose. IUDs, whether hormonal or copper, also show fast fertility return after removal, and studies have found no relationship between how long the IUD was in place and the time it took to conceive afterward.

The notable exception is the injectable shot (Depo-Provera). Because the hormone is deposited into muscle tissue and releases slowly, the last injection takes roughly three months to wear off on its own. After that, the median additional delay to conception is about 5.5 months. So from your last shot, you might be looking at eight to nine months before you’re likely to conceive. This doesn’t mean the shot damaged your fertility. It simply takes longer for the drug to leave your body.

The implant (Nexplanon) falls somewhere in between. Ovulation typically returns within weeks of removal, and most women can conceive within the same general timeframe as pill users.

Why Some Women Struggle After Stopping

If birth control doesn’t cause fertility problems, why do some women have trouble getting pregnant after going off it? The most common explanation is that hormonal contraceptives can mask underlying conditions that were already affecting fertility.

Polycystic ovary syndrome (PCOS) is the clearest example. Combined oral contraceptives are actually the first-line treatment for PCOS in women who aren’t trying to conceive. The pill restores regular periods, reduces excess androgen levels, and suppresses the hormonal imbalances that characterize the condition. While you’re on it, everything feels normal. When you stop, the irregular cycles and ovulation problems that define PCOS come back, and it can seem like the pill caused the issue.

The same is true for endometriosis. Hormonal birth control suppresses the tissue growth and inflammation that cause pain and can interfere with conception. Stopping birth control doesn’t create the endometriosis; it simply removes the treatment that was keeping symptoms under control.

Age is the other major factor. Many women start birth control in their late teens or early twenties and stop in their thirties. A 34-year-old who has difficulty conceiving after ten years on the pill isn’t experiencing a side effect of the pill. She’s experiencing the natural, well-documented decline in fertility that begins in the early thirties and accelerates after 35. This would have happened regardless of contraceptive use.

What This Means if You’re Planning a Pregnancy

If you’re on the pill, patch, ring, IUD, or implant, you don’t need to stop months in advance “just in case.” Fertility returns quickly enough that stopping when you’re ready to start trying is a reasonable approach. Some women do choose to stop a cycle or two early so they can track their natural cycle length and ovulation timing, which can be helpful for planning but isn’t medically necessary.

If you’re using the injectable shot and want to conceive soon, it’s worth factoring in the longer clearance time. Switching to a shorter-acting method six to nine months before you want to start trying gives the drug time to leave your system.

If your period hasn’t returned within three months of stopping most methods (or within nine to ten months after your last injection), or if you’ve been trying to conceive for six to twelve months without success, the issue is worth investigating. The cause is almost certainly unrelated to your birth control history, but identifying conditions like PCOS, thyroid dysfunction, or other ovulatory disorders early gives you more options for treatment.
