Hi, my girlfriend takes birth control pills. One night, we had sex and when she arrived at home she realized that she hadn t take the pill from the day before. Then, she took two pills. The day after shw took an emergency contraception pill, and continued taking the birth control pills. Fourteen days later (three days ago), she began to have a small bleeding, that is still happening (but very small, and today is the third day since it started). Is it expected?
