Your cycles should return within about three months of stopping birth control, if not sooner. You should have a cycle within one to three months of discontinuing most forms of reversible birth control.
If you stopped birth control and haven’t gotten a period yet, you may want to take a pregnancy test first. You can get pregnant the very next month after stopping birth control.
For example, if you have been using the pill for a short or long time you are likely to experience a temporary delay in conception, but this does not affect your chances to fall pregnant.
Fertility is slightly reduced during the first couple of menstrual cycles after stopping the pill, but after that, monthly fertility rates quickly return to their usual level.
For those using other contraceptives such as the Uterine Devices (IUD’s), Implanon and Depo-Provera long-term fertility is maintained. Most contraceptives are associated with a temporary reduction in fertility.
However with the injection of Depo-Provera it takes an average of 9-10 months before ovulation returns and therefore it may take longer before you can fall pregnant. If you want to become pregnant in the next 12 to 18 months, it is recommended that you use a different method of contraception.
