Raynauds Syndrome and thin uterine lining

Two trials for FET have been a no-go because my lining is too thin. My docs have upped the estrogen dosage, added viagra (!😂), baby aspirin, and vitamin e. Still can't get my lining past 6.5. I was looking into solutions and saw something about Raynauds Syndrome affecting the lining. I was diagnosed with that circulation condition years ago, but didn't think to mention it until now.
