Crinone is progesterone & progynova is a type of estrogen - neither of which are measured on standard HPTs.

How many days past transfer are you? I assume you're at the end of your TWW? You can always check with a few different brands of HPTs - but in the end, it's the blood test that will confirm it or not.

Just quietly, it does sound promising! I had false positive when I was on pregnyl, but obviously that's because is hcg!
