I took progesterone 200mg 2 days after IUI, 2x a day and continued until 12 weeks pregnant. I am currently 19 weeks pregnant.
I started the second day after my iui. My first iui the dr had me on 200 oral progesterone. I didn't get pregnant. The next RE had me on Crinone, the gel, which is 90 mg (but I don't know if the doses are equivalent since one is oral and one is a gel)-- I also didn't get pregnant. I did get pregnant on my own (no meds or iui) in Jan and was on 400 mg oral progesterone and then up to 800 mg when my progesterone decreased. However, I miscarried in Feb.
I think the jury is kind of out on progesterone. Some REs think it may help, can't hurt, while others (like my current RE) doesn't like to put someone on it unless their day 21 progesterone is low.
What type are you taking? Oral? Gel? Suppository?
oral. Will see. Tomorrow is day 7 post IUI. Another 5 - 7 days to wait.
