It's not 8 days since my embryo transfer & I'm starting to feel the need to test a bit.... So what I wondered was when did everyone test? I mean HPT not BT, as we have the BT already booked in. I had Pregnyl as my trigger injection on the 13th so 15 days ago, would it be out of my system yet? Or does it take a long time & that's why the BT is after the normal 14 days after conception?
