I need help last week I had really bad left flank pain that came and went and between achy and throbbing. Today I thought I started my period which I am early and usually on time like clock work. It was light pink which I found very odd bc I'm 30 and never had this happen before so I put a tampon in. Well for bed time I put a pad on but there was nothing on my tampon. Does anyone have any suggestions? Or happened to anyone else?
