I had my period last Jan5. It lasted the usual 6 days. The weekend my period ended(Jan13-16), I had a mix of protected and unprotected sex, but my boyfriend did not cum. By Tuesday, I took emergency birth control just in case. Then the next week, I got my period again. It only lasted for 3 days (1st day-normal flow, 2nd day-heavy and 3rd-light) my period usually lasts for 6days. And i got this period on day 19 of my cycle. Around 10-11 days early. Is this normal? Is it my period? When should I expect my next period to come?:
