Hi, I need some advice ladies. I had a FET last Monday morning. This was a 5 day blasto. After transfer they gave me a shot of Pregnyl in my tummy to assist in progesterone for the TWW. I know Pregnyl can give a BFP in the early days of the TWW. I'm now 8DP5DT and I just pee'd on a stick (lunch time, not first morning urine) and it's clearly a BFP. How long does Pregnyl take to get out of my system? ......is it real or is it the pregnyl? Any advice ladies.......going slightly insane now.
