Yep. After Lap and Dye I was told I had multiple instances of endo all over my left side. Now, at my last fertility appointment, it was implied that the endo is slightly worse than I was led to believe. Nothing is blocked but it is on and behind the ovary.
Treatment depends on severity. You can have it removed. They normally remove what they can during L&D but other than that the only treatment I was told was to go on the pill. Endo thrives when the hormone balance sways towards estrogen. Might explain why I had barely any endo pain during my time on Clomid, actually.
