Hi Infinity,
Wishing you the best of luck for your BT on Friday. I can't say if progesterone mimics pregnancy symtoms having never had a BFP, but I have seen lots of woman say it does. Everyone says 'ignore all symptoms', as frustrating as it is. For me however, progesterone never delays AF, no matter how much support I have, and I have had up to 4 x pessaries a day. I hope the rest of the week speeds by for you and ends with a BFP. Good luck.
