To be honest I'd be making an appt with your gp and perhaps trying out a different pill.Is it a mono type pill? There the ones that they say keep us 'levelled' out so we don't get pms!! The mono type pills do have that sort of affect on some people, like my lil sister. She had AF then 2 wks later got AF again. SO she went back onto a triphasal type pill and hasn't had a prob since. I'd stop taking that pill if its affecting your body that way, noone wants AF for that long and that often.
