So last month I moved my period back a week than it was supposed to be. But this month it's way heavier than it usually is... is this normal? I mean it's not breakthrough bleeding right cause it's not in between when its supposed to happen? I've been on BC for more than 6 months and last time was the first time I skipped my period so I could understand how I might get a normal period or whatever this time, I guess I'm just worried it'll last for more than a week.
