I had unprotected intercourse and had ipill , usually I get periods on 24th day of last period , this time my period skipped for 15 days . I had urine pregnancy test and its negative. I consulted gynecologist and she gave me med for periods Deviry 10 mg . I had deviry for 6 days straight, still no periods. Why is this happening ? is it because of ipill ? when can I expect to have periods? its been almost 35 days .
