I posted on INFERTILITY but also wanted to ask you girls.. I dont know how to attach link?

When I first went to my RE my progesterone was good. When I got pregnany and had a m/c progesterone also never seemed to be an issue. I just did my first IUI/Injectible cycle. I was told I could do a prog test on day 5 if I wanted to but I didn't have to! Anyway I did and got the results today since I went late yesterday It's 6.4 and I was give Endometrin.

I am now curious about all my past IUIs and what m,y prog was and if these suppositories will even help today it's 6 days past IUI?????

What are the side effects and do you think it will help?

THANKS
