Q: I haven't had my period since I stopped the pill four months ago, should I see a doctor?

A: If your menstrual period doesn't return, or if it continues to remain very irregular for several months, that may be a sign that you haven't started ovulating regularly yet. "Post-pill amenorrhea," the absence of a menstrual period after you stop the pill, is seen in about one in 30 women who stop taking the pill. It's usually suggested that you see your doctor if your period hasn't come about three to four months after stopping the pill.
