I was diagnosed with mild endo earlier this year and had it removed via lap after years and years of painful periods. DH and I have been TTC for just over 2 years now with no luck. We did have a chemical pregnancy a few months after surgery, but have now opted to try IUI. I've got five more days of this cycle before BT to see if it was successful. I know my aunty had endo and she had no trouble conceiving or giving birth. I guess you won't know until you try... Good luck!
