I agree with the other ladies that a lap would be a good idea if you know you have endo. Have you spoken to your Dr about it yet?

We were TTC#1 for years and even did multiple IVF before my lap and none of it worked. After a little over 3 years I had a lap to diagnose and treat my endo and was pregnant 2 months later (via IVF). We have since had a natural conception too (our recent m/c, which had nothing to do with my endo) because the endo hasn't had a chance to grow back yet. The lap made a world of difference to our TTC efforts.

Presumably you had a lap in the past when your endo was diagnosed? That's the only way it can be officially diagnosed.
