I may be the only one still coming here but I have a question if anyone can answer. If you have progesterone issues and know your risk of MC is higher after conceiving, when do you start taking or using progesterone to help? Right after ovulation or after you get a BFP? I was using the cream a while back but my DR said I was using it wrong and to just stop.. buuuut, I don’t want to not use it after I ovulate and risk having a MC before I can get some progesterone in my system if that makes sense🥴
