Periods...

Laura

Okay so, I've gotten my period twice in the last 2 to 3 weeks... the first was normal and 4 days long the second is on going but it's heavy and I'm on the 2nd day. Usually I get a period once a month and it's light and lasts 3 days max. I'm on the pill which I know causes irregular periods but this has never happened before. And I haven't been missing pills either...
