Welcome & a big congratulations! I used Crinone until the day of Bt when I ran out. Then they said my progesterone levels were fine. I'm sure if your levels were low they would have told you. If your worried just ring the clinic. I think it's natural to feel a bit worried. I know I do because it's still early yet but I also feel very positive. I don't think I'll totally believe it to we do our scan. Good luck with the second Bt!
