I am so sorry you are going through this.

I have had 3 surgeries (all laparoscopic) for my endometriosis.
I've had a major reduction in my pain and other related symptoms. I don't know if my surgeries helped me fall pregnant, I definitely haven't had to do IVF.

My advice would be to find a Gynae who is experienced with endometriosis and consult with them. Many surgeons will use a laser to 'burn off' endo patches but what you really want is for the endo to be 'excised'.

I mean no offence but your FS sounds a bit wishy washy what with changing her story all the time. You need someone on your side who is going to give you answers and consistent advice.

My recommendation would be to see a Gynae with much experience in endometriosis.

Good luck and I hope you get some positive news asap!
