Hi Ausgirl and welcome! I'm sorry to hear that you've had such a hard time of it. The only way to properly diagnose and treat endo is with a laporoscopy and hysteroscopy (where they insert the camera into your vagina to have a look inside your uterus as you may have endo inside there). A D&C (curettage) is usually also done at this time. You may even need to have a dye inserted (where they inject dye into your fallopian tubes to check for blockages). They will remove anything that they find at the same time.

I have always had great success after my two laps (my last one was in december last year) and the quicker you get onto it, the better chance you have of successful treatment and pregnancies when the time comes for you.

One thing I would also suggest is that even though you are not sexually active that it might pay to have a pap smear done because it sets a baseline of sorts for any future ones and not being sexually active doesn't exclude you from being at risk. I started having pap smears before I was sexually active and it wasn't a concern to me that I was still a virgin at the time kwim because it was just like any other medical procedure, but that's up to you.

Good luck and don't be afraid to ask any more questions as you have them.
