Hi,
Welcome to ehealthforum,
Sometimes your normal fertility can come back early (depending on type and duration of birth control method used), and you can have ovulation (egg release from ovary) in your immediate cycle after stopping with your birth control use. Wait and watch for your next periods. If you suspect to be pregnant already (if you had been sexually active after stopping with birth control use), look out for development of any new symptoms suggestive of pregnancy. If you do not get your next periods on time, or if you get abnormal periods or if you develop symptoms suggestive of pregnancy, you should consider visiting your gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
Take care.
