If you've come off contraception and you're asking the question "stop birth control how long to conceive," the honest answer is: for most women, the same as anyone else who's just starting to try. The waiting time depends almost entirely on which method you were using, not on damage left behind by it. Patients who come to me with this worry are often surprised to hear that decades of evidence show no long-term fertility cost from hormonal contraception.
What does vary is how quickly your cycle (and ovulation) wakes back up. Below is the method-by-method picture I share in clinic.
How Soon Can I Get Pregnant After Stopping the Pill?
For the combined oral contraceptive pill, ovulation usually returns within one to three cycles, and sometimes during the first cycle off the pill. The progesterone-only pill (POP, or mini-pill) clears the system within days, so fertility can return almost immediately.
By around three months off the pill, most women are at the same baseline fertility as women who never used it [src]. The pill doesn't "stay in your system" and it doesn't deplete your eggs. Those ideas come up often, but the data doesn't support either one [src].
In my clinic, I see women blame the pill for slow conception when the real factor is usually age, or undiagnosed PCOS that the pill was masking by giving them predictable monthly bleeds.
IUD Removal Fertility Return (Copper and Hormonal)
The IUD removal fertility return picture is one of the most reassuring across all methods.
The copper IUD is non-hormonal, so fertility returns immediately. Many women ovulate in the same cycle as removal. The hormonal IUD (Mirena, Kyleena) takes a little longer because the local progesterone needs to clear: cycles typically resume within one to three months, with research showing an average time to pregnancy around 4.4 months and roughly 97% of young, healthy women pregnant within 18 months [src].
You can start trying the same cycle the device comes out. There's no need for a "washout" interval.
Implant and Depo Fertility Return Time
This is where the methods split.
The implant (Nexplanon) releases a small dose of progestogen, which clears within about a week of removal. Most women ovulate within three to four weeks.
The Depo-Provera injection is the slowest of all the common methods. Average return to ovulation is about five to seven months after the last shot, and it can stretch to 12 to 18 months in some women. This delayed clearance is not infertility, and it doesn't damage future fertility, but it does matter for planning [src].
Patients who come to me wanting to conceive within six months, I usually suggest switching off Depo at least 9 to 12 months before TTC, just so the timeline feels realistic rather than worrying.
A common question is "how long does Depo take to leave your system." The drug itself is metabolised within weeks, but its suppression of the hormonal axis can persist for many months after that, which is what creates the longer delay.
Post-Pill Amenorrhea: When Periods Don't Return
Most women have a recognisable cycle within three months of stopping any method. Post-pill amenorrhea (no period for three months or longer after coming off the pill) is the point where I'd recommend investigating [src]. Common findings include:
- Undiagnosed PCOS, where the pill was hiding underlying irregular cycles. Our guide on how to know if you have PCOS walks through the warning signs.
- Low body weight or recent significant weight loss.
- Thyroid dysfunction.
- Hypothalamic amenorrhea from very intense exercise or under-eating.
Post-pill amenorrhea is rarely a pill side effect. It's almost always something the pill was concealing.
What to Do in the First Three Months After Stopping
A short, useful checklist:
- Start folic acid 400 mcg daily (5 mg if you have qualifying conditions such as diabetes, a previous neural-tube affected pregnancy, or you're on certain medications). See when to start folic acid before TTC for the detail.
- Track one or two cycles to learn your fertile window.
- Don't expect period regularity in cycle one, especially after long-term hormonal use.
- Book pre-conception bloods with your GP. The full pre-conception health checklist covers what's worth asking for.
When to See Your GP or Doctor
Book an appointment if:
- No period three or more months after stopping any method.
- You're under 35 and have been trying for 12 months without success.
- You're over 35 and have been trying for 6 months without success.
- Your first cycles back are very heavy, very painful, or extremely irregular.
If you're not sure where you sit on that timeline, our guide on when to see a fertility specialist gives clearer thresholds.
NHS vs US Pathway
UK / NHS: Removal of IUDs and implants is free through your GP or sexual-health clinic. NHS fertility investigations typically begin after 12 months of trying (6 months if you're 36 or over).
US: Device removal is usually covered by insurance but copay varies. The ASRM definition matches: a fertility workup is offered after 12 months under 35, or 6 months at 35 and over.
What This Means for You
The pill is rarely the reason couples take time to conceive. If you've been asking how long after you stop birth control to conceive, the answer for most methods is weeks; for Depo it can be many months. Give your body three months, track your cycles, and check in with your GP if periods don't return.

Will pill use cause miscarriage in a future pregnancy?+
No. Large studies show no increased risk of miscarriage in pregnancies conceived after stopping any hormonal contraceptive.
Should I have a 'washout' cycle before TTC?+
There's no medical need to wait. You can try the first cycle off the pill. Some couples prefer to wait one cycle to confirm dating, but that's a personal preference, not a clinical requirement.
Can I TTC the first cycle off the pill?+
Yes. Fertility can return immediately, especially after the mini-pill or copper IUD. There's no evidence that conceiving in the first cycle harms the pregnancy.
Does long-term pill use affect egg quality?+
No. Egg quality is driven primarily by age. Decades of follow-up data show no decline in egg quality or ovarian reserve from long-term combined-pill use.
