Trying to Conceive After Coming Off Contraception

The honest picture, with numbers

The fear that contraception has done lasting damage is extremely common and, for almost every method, unsupported. The largest prospective study on this question followed 17,954 women in Denmark and North America and reached a clear conclusion: some hormonal methods delay the return of fertility by a few cycles, and lifetime length of use of hormonal contraception was not associated with fecundability. Ten years on the pill does not cost you anything that one year does not.

A separate systematic review and meta-analysis pooled 22 studies covering 14,884 women who stopped contraception intending to conceive and found a 12-month pregnancy rate of 83.1% (95% CI 78.2% to 88%). Broken down by method: 87.04% for oral contraceptives across five studies and 11,636 participants, 84.75% for IUDs across 2,374 participants, 77.74% for injectables (only two studies and 139 participants), and 74.7% for implants — 83.45% once one outlier study was excluded. The review's own summary was that return of fertility in the first year was not significantly different between hormonal methods and IUD users.

Set that against the general population baseline in NICE NG257: 86% of women aged 30 to 34 conceive within 12 cycles, 87% at 27 to 29. The post-contraception figures sit essentially on top of the general figures.

It is worth being precise about what a delay of a few cycles actually means. It is not a reduction in your chance of ever conceiving. It is a shift in when the counting usefully starts. Over twelve months the cumulative figures land in the same place as everyone else's, which is why the practical advice below is about timing your decisions rather than repairing anything.

What actually affects it, by method

The delays that do exist

The prospective cohort measured delay in return of normal fertility relative to barrier methods:

• Injectable contraceptives: the longest delay, 5 to 8 menstrual cycles (fecundability ratio 0.65, 95% CI 0.47 to 0.89). The NHS puts the same point plainly: it can take up to 1 year for fertility to return after stopping the contraceptive injection.
• Patch: about 4 cycles.
• Oral contraceptives and the vaginal ring: about 3 cycles (oral fecundability ratio 0.94, 95% CI 0.90 to 0.98; ring 0.92, 95% CI 0.82 to 1.03).
• Hormonal and copper IUDs and implants: about 2 cycles (hormonal IUD 1.14, 95% CI 1.07 to 1.22; copper IUD 0.97, 95% CI 0.89 to 1.06; implant 1.03, 95% CI 0.85 to 1.23).

The NHS states that when you stop taking the combined pill, fertility usually returns to previous levels after about a month, and that for the progestogen-only pill it usually takes about a month for your chance of getting pregnant to return to what it was.

What contraception was hiding

This is the part that rarely gets said. Hormonal contraception imposes a regular bleed and suppresses symptoms. When you stop, you may be meeting your actual cycle for the first time in a decade — and if it is irregular, or if painful periods return, that is not a side effect of stopping, it is the underlying pattern reappearing. PCOS and endometriosis are both commonly masked this way. The NHS lists hormonal contraception among the causes of irregular periods, which is why the first few months can be genuinely ambiguous.

The useful consequence is that a difficult first few cycles after stopping are worth recording rather than dismissing. If your periods come back heavy, painful, very irregular or not at all, that is information about you rather than a temporary artefact of the method, and it is the sort of history that changes what a clinician does at a first appointment.

The practical business of stopping

Pills, patches and rings you stop yourself, on any day you choose. An IUD, IUS or implant has to be removed by a clinician, and appointment waits vary — book that removal before you want to start trying rather than after, because a five-week wait for a slot is five weeks of the year you will later be asked to count. The injection is different again: you stop by not attending for the next dose, which is why its effect tails off across months instead of ending on a date you can name.

Age has moved

The other quiet variable is that time has passed. If you started the pill at 24 and stopped at 36, your cycles have not changed nearly as much as your age has. NICE recommends using maternal age as the initial predictor of the chance of conceiving naturally, and at 36 the referral threshold changes.

What does not matter

Duration of use, according to the prospective cohort. There is also no evidence-based reason to have a wash-out period, or to wait for a set number of natural cycles before trying, unless your clinician has given you a specific reason relating to a medication or vaccination.

What to do next

1. Start folic acid before you stop contraception, not after. The NHS recommends 400 micrograms daily, ideally from three months before conception.
2. Record dates from the day you stop. The referral clock starts when you begin trying, not when your cycles settle, and you will need those dates.
3. Give the injection a realistic timeline. If you have been using the contraceptive injection, expect months rather than weeks, and plan the stopping date accordingly.
4. Do not wait for perfect cycles before trying. Intercourse every 2 to 3 days, as NICE recommends, works without a predictable cycle.
5. Check rubella status and cervical screening while you are in the system — NG257 recommends both around this point.
6. If periods do not return within three months of stopping a method other than the injection, treat that as a reason to be seen rather than to wait.

When to seek help

The thresholds do not change because you were recently on contraception. NG257 recommends offering both partners assessment and investigation after 1 year of unprotected vaginal intercourse, and referral at first presentation if the woman trying to conceive is 36 or over, or if either partner has a suspected or known clinical cause of infertility. ACOG advises evaluation after 12 months, or 6 months over 35.

Ask to be seen sooner if your periods have not returned three months after stopping any method other than the injection, if they return but are irregular — gaps under 21 days or over 35 — if they return with severe pain, or if you are 36 or over and have only recently stopped. The one genuinely common trap here is spending a year waiting for cycles to normalise before starting to count. Count from the day you stopped.
