There is no evidence birth control reduces fertility. Clinical studies have suggested that pregnancy rates after long-term birth control use are nearly identical to those in women who’ve never taken birth control. Specifically, the European Active Surveillance Study on Oral Contraception reported a pregnancy rate of 79.4% within one year of stopping birth control compared to a pregnancy rate of 81% in the control group.

There is evidence that long-term use of birth control pills can reduce the risk of endometrial and ovarian cancers. There is also a possible reduction in PCOS rates, cysts, and endometriosis, but your chances of getting pregnant are not reduced. If you find your menstrual cycle is irregular after you stop taking the pill, give it some time. Ovulation controls menstruation and the pill stop ovulation. It can take some time to return to a normal ovulation cycle.
