So, I'm just curious from others who have been on progesterone. I take 200 mg of prometrium starting at day 18 of my cycle, and stop as soon as I get a bfn. I have been doing this for the past 5 cycles now. So far, I had one chemical pregnancy, and no luck getting pregnant other than that. I never had issues getting pregnant before starting the progesterone, and got pregnant the 1st cycle we tried every time, with a total of 4 pregnancies, 1 ending with my dd. I am thinking that the progesterone is screwing up my body, and my chances of getting pregnant. I'm thinking about stoppin taking it, and just start it once I get a positive test. I'm going to ask my dr next week for her opinion, but was wondering what others think? I appreciate your input, because I'm getting impatient over here, and ick of the let downs every month!
