Nikki, I was diagnosed with endo, after TTC#2. My FS said my endo wasn't the typical chocolate cysts, but the white stuff and it was a complete sheet, that he was too afraid to remove, for fear off breaking through it and then doing damage to my reproductive organs.

I went on Synarel for 3 months! Then we started on IVF. We were fortunate to have a BFP from our first cycle. I spent the first 11 weeks using crinone (for the TWW) then switched to the pessaries, along with taking Progynova and Provera tablets.
I had read that women with endo issues, usually need some progesterone support during the first tri.
