You had sex before and didnt bleed.After a gap you bleed again.No past STD history.

 i really need some advice here i am WORRIED SICK at the moment. im 22. have had sex with only one guy who took my virginity a year back..and well the thing is we dont have sex that regularly.but offlate whenever we do..i end up bleeding.it is not a lot.some spots occur on the bedsheets and all im wondering is that is it because something is wrong with me? a girl cannot grow her hymen back right? thats not possible.so what could be the reason? i live in a place where its next to impossible to go see a doc.so i really need some help here.i have a large labia majora..on the right actually.the left one is just normal shaped.

Before when we had sex i didnt bleed so much.This has been happening now and the gap is 1 month or sometimes even more.

I REALLY NEED someone to tell me its okay and i shouldnt worry.
