I want to hear from someone who has had endometriosis or other similar problems with their womanly parts... !?

Ive been having herendous cramps to where I throw up, turn white, get clammy, and faint. I will curl up in a ball and pray to god I don't die because the pain is so herrendous. I'm afraid I have endometriosis or cervical cancer or something of that nature and I'd really like to hear from some people who have gone through these things and what their symptoms were... I'm just kinda scared to find out. I'm going to go to a gynocologist, hopefully, next week but in the mean time I'd really like to hear from you guys.
