Hi, I am doing an FET cycle, this is my 4th, I have always had a problem with the lupron not supressing me and my estrogen being too high. Always, in the past, Re would keep me on the lupron anyway, checking weekly and eventually my lining would just get ready on its own and I would start estrace/PIO and have my transfer. This time, all has been going as usual (estrogen too high, staying on lupron) and when I went in last week and again today my lining was thick (over 8) but not trilaminar, this has never happened before. RE has told me to take 100mg progesterone tonight and come back in a week. Will this help to make my lining trilaminar or will I need to have a period and start my cycle all over again? I have complete confidence in my RE, just wanted a second opinion. Thank you in advance.
