This depends on the birth control method you use and how your body responds. If you have an IUD removed, it is possible for you to become pregnant the first cycle after its removal. Since IUDs don’t normally affect ovulation, it is actually possible to become pregnant just a few days after removal. The same goes for NEXPLANON, the arm rod contraceptive. Once the rod is removed, you can become pregnant within the first cycle.
If you take the combo birth control pill, which contains both estrogen and progesterone, or a progesterone-only pill, you can become pregnant also within the first cycle, as ovulation will resume within the month after you stop the pill.
Your chance of becoming pregnant in any given month of trying is around 20% or less, even if everything is normal. So, it’s not likely that you’ll become pregnant right after stopping birth control, but it is possible and you don’t need to stop it until right before you would like to become pregnant. In some cases, your menses might not resume after stopping these forms of birth control and that’s not likely to be due to the birth control, but to an underlying ovulation or fertility problem. If your periods don’t become normal after stopping any of these methods of birth control within two or three months, you should see your doctor. Even when everything is working well, it still takes several months for the average couple to get pregnant. If you’ve tried for a year and not become pregnant (or six months if you’re over the age of 35), you should see your doctor for a fertility evaluation.
When you stop the Depo-Provera shot, however, you may not have an immediate return to fertility. This is one of the down sides of the shot. It can take some women several months or even well over a year for ovulation to return. The contraceptive effect of each shot lasts for 12-15 weeks, which is why we recommend that patients get the shot every three months. Some patients choose to stop the Depo-Provera shot six months or more in advance of a planned pregnancy to avoid an unnecessary delay in conception. Barrier methods such as condoms or the diaphragm, as long as they are not used, allow for the possibility of immediate conception if you ovulate regularly. Remember, becoming pregnant may take up to a year even if there are no issues. Don’t get discouraged and make sure you are talking with your doctor throughout the process if you are worried about anything or suspect something is wrong, especially if your menses aren’t regular.
