I have my FET on tuesday and have been taking estrace and just started taking progesterone suppositories and PIO on thursday. I had my lining check on tuesday and it was at a 9. For some reason i am feeling crampy today and super sore boobs and im not sure if its the new progesterone/estrogen combo medication that is causing the cramps. but i am super worried tbh. Did anyone else feel crampy while taking these medications? My clinic is closed until monday so i cant even call them.
