My period was due yesterday (Sunday). But it started Saturday night, which is no biggie at all. Anyways it was light & brown like how a period usually starts. Long story short, today is day 2 & im bleeding through super plus tampons every 25-30 mins. I texted my bff & she told her mom cause she works in a doctors office & she asked if I was pregnant & said that it sounds like I'm miscarrying but AF came basically right when it was due. I ovulated, had PMS and allat. But I did have unprotected sex the day I ovulated but he didn't cum inside me but it was unprotected & im not on the pill or anything. But this bleeding is ridiculously heavy. If I'm not miscarrying then why such a heavy bleed?
