Lil - I'm sorry your progesterone is not where they want it to be but the progesterone suppositories will help. Your HCG number sounds great!
As far as the suppositories, the first time I put one in was a little awkward but you get used to it, doing it three times a day. I'm assuming your pills are like little oval bullets so I just took my middle finger and (tmi) pushed it up as far as it could go. I tried to get it as close to the cervix as possible. Once it's in there you can't feel it. The only suggestion I would have is to wear a panty liner because there does tend to be um leakage

. Not a lot but enough that you don't want it in your underwear. I would also keep the suppositories in a cool place because they melt very easily. Let me know if you have any more questions. They really weren't that bad and I'm sure they'll keep things nice and comfy for the bean.
