Help.

so my menstruation cycle on and lasts five days typically. for 28 days now, I’ve had my period straight heavy flow and everything. two months ago, I tried oral birth control for a month. that next month my period was completely normal. but now, I’ve had my period straight and I don’t know if this shits normal. i’m running out of ideas and tampons so someone please help me and tell me what’s going on😂😂

A little ideas you probably wanna know, this is never happened to me before and I am 17((:
