I had my frozen embryo transfer last Tuesday so I am 8 days past my 6 day transfer. I gave in and decided to test today. I'm a bit confused... the test instructions said... wait 3 minutes if nothing shows to wait a few more minutes but not to read it after 10 minutes. So I started timing at 7:02am with first morning pee. After 3 mins I saw nothing then I started noticing something around 7:07am...I took photos over time. Not sure what to think. Here are the photos. Hope the photo works. Is this evap? Possibly a false positive? Anything? Please I need advice.
