period problems

Ashley
Okay so my period has been weird lately. I've had problems with it in the past and when I was on birth control it was okay. I haven't had my birth control since around October. I can't afford it right now though I know I need it back. Anyways so my period started on April 15 and ended on April 25 then it started again on may 11 and is still going. I'm bleeding quite a bit durning the day but at night there's nothing there. I have had sex and been very stressed lately. Anyone know what this could be from? I haven't cramped at all just blood
