hey, all! Not sure if this is the right board for me, so please let me know if not

I am 28yo, married to DW for 2 years. I went through IVF 4 years ago with great results. However, the transfer hasn't quite been as easy
Hysteroscopy found that I have a uterine abnormality: unicornuate uterus, with no horn. 2 functioning ovaries, only one with a tube connecting it to the uterus.
FET #1 7/13: cancelled due to uterine lining not thick enough
FET #2 5/17: estradiol pills, minivelle patches; cancelled due to my estrogen levels peaking at 375 and dropping as well as my lining breaking down, or "moving" as my RE says.
FET #3 7/17: only minivelle patches; cancelled due to my lining moving and breaking down again, even though it was the correct thickness.
I went in to this thinking it would be easy, and it has been anything but. I have always had issues with my reproductive system (wonky periods in HS, abnormal paps, cervical biopsies, etc), but I never thought I would fit into an infertility community. But I feel like maybe I do at this point
