Hello, I'm 21 years old and my gynecologist thinks that I might have endometriosis, because I have very heavy and painful menstruations with clots and brown discharge. I use oral contraceptions lindynette 30 But recently I have noticed these simptoms: sometimes I expierience pain with intercouse, and sometimes there is blood after intercourse, I feel pain when I poop on menstruation, sometimes I feel at same time back and plevic pain in the morning, but it later disappears when I move, my discharge changed and sometimes the discharge is mucus like in bright yellow color, the brow discharge sometime appears in the midle of cycle and on last 3-4 menstruations there is blood with mucus in it, first day of menstruation I feel pain and bleed heavily, and on the second day - blood with mucus. I'm going to see gynecologist after my period, but I'm very concerned. So I would like to ask is these symptoms could be because of endometriosis? What could mean this mucus in menstruation blood? Sorry for my bad english
