If you haven't been on birth control you have been ovulating for a year, you just didn't have your period. Ovulation can have some very subtle symptoms but for the most part it is a non event. Why do you think people buy ovulation predictor kits and the like.
Oh hun, how old are you? You do not have to have a period to ovulate! An egg that is not fertilized is absorbed back into your body. Do you know how many people I know who got pregnant when they were nursing because they didn't know this either?
