Have you tried doing estrace as a suppository instead of the patches? I tried the patches, had an allergic reaction and dropped my lining 3 days before egg retrieval. Tried estrace orally and had super high E2 levels but a lining that never got above 6. Next up estrace as a vaginal suppository. Lo'behold I can build a lining up to 13! At my max dose I was doing 2mg 3x daily, and it took me 16 days to get a lining up to 13. So there is always hope.
Now some woman only respond to Del Estrogen (injections) those are unavailable here in Canada, so I have no experience with that. Sorry I know this doesn't make this cycle cancelling any better, but I wanted to let you know you are so not alone on the lining issues.
All my best to you!
