Q&A: Ovulation After Birth Control?

If I am getting my period 28-30 days since being off birth control, can I assume I am ovulating regularly?

Generally, if your  menstrual cycles are regular, they are presumably ovulatory. But, it is not absolutely conclusive, as subtle abnormalities can occur within cycles. Over-the-counter testing with ovulation predictor kits can be use to verify that the LH (lutenizing hormone) surge signaling ovulation has occurred. If in doubt, consult a specialist. (Look for one certified in reproductive endocrinology and infertility by the American Board of Obstetrics and Gynecology.)
