How long will it take for my ovaries to start releasing eggs again after BC?

Varies. Your fertility can return as soon as the month after you stop your pills and some women are more fertile just after stopping birth control pills. In other women it can still be normal to take up to one year to start having pills again. This is called post-pill amenorrhea. Unfortunately there is no way to predict which will be the case with an individual woman. Wish I could be more help.
