Maybe You Can? I've Had 12 Months Of Symptoms Bloating

Maybe you can? I've had 12 months of symptoms bloating lots of pain up my right side and in my right groin area, spotting, mucus upper abdo pain, changed bowel movements and more. My CA125 has gradually risen from 10 to now 23 over a 12 month period. Many tests but nothing can be seen. Last Gyno (no.8). Said it was endometriosis as diagnosed a few small spots when I had a laparoscopy in June last year. Put me on Depro Vera 2 weeks ago. Am nauseous and pain is still present. If it was endo how long before its meant to work ? I'm booked in for more exploratory surgery on a few weeks but scared to death. Just want it all out but Gyno reluctant. Help ??
