My mom had endometriosis but didn't find out tills she was 50 and so she got a hysterectomy and no she's better than she was but I researched it and the doctors say there's over an 90 present chance that if you have endometriosis that it will be passed on to your daughter I have been experiencing pains in my side for the past 2 years and I'm 15 and got my period when I was 11 and I have always been extremely irregular with my periods and they are alway heavy and very painful I also have a pain in my side and it happens at no particular moment.

I'm just wondering is this endometriosis or am I over reacting please let me know?
