Hello, I'm 17 years old and I have been dealing with constant excruciating pain in my abdomen (left, centre and right side) since last year in August. I've been through hell trying to find out what's been causing this pain. I have always had very painful periods to where I would nearly faint from the pain, very irregular periods, as well as being very heavy for 5 out of the 7 days of my period. At first (after some scopes) they diagnosed me with IBS, but after a while of doing test to find the trigger i was still having no relief. I was put on the pill in case it was endo but there's also been no relief. I've had an ultrasound for my uterus and they didn't find any indication that I had endometriosis (most likely too small to see any). I am in year 12 and I've already missed so much school, I'm going to see a gynaecologist in a week to beg for a laparoscopy because I need it confirmed or denied. When reading people's experiences with endo I relate to it so well which is why I 80-90% believe I have endometriosis.
