Dubis I also have fx and tx for you too! I have endometriosis too and it took 18mts post mc last time. But I did get there surprisingly. I really thought there was no hope. I'd already been operated on and in addition have thyroid problems and am permanently anemic. I'm not sure how but it did happen.
There are diets that help with endo, I expect you've tried that, but my cousin who after 15 years of ttc and on 4th round of ivf finally did succeed with twins after she went on wheat and dairy free diet. I bit drastic but it worked. I think the best thing to do it to try and keep an open mind to all these things when it seems so bleak.
I had a Wave of nausea hit me earlier this eve and poas, another result with the look of a bfp but smudgey. I don't know why I'm testing anymore because I really think I'm out this month now. Surely it must be a bad batch of tests as why would I get such conflicting results. 3 tests left and Then they are officially gone!
