Hi, can I answer your health question? Please type your question here... I'm 13 years old. I have really really bad period cramps all the time and my doctor told me it's normal but it's soooo bad. I have almost all of the symptoms of endometriosis. I was feeling inside my vagina and it's really tight and it kinda feels like there's scar tissue there, I was hoping you could tell me what scar tissue feels like so I can see if that's what it is.
