It is probably a bit too early to test although some women do get BFPs as early as d10. Most don't though and you will more than likely get a negative and if you are anything like me, that will mess with your head. I can understand your burning desire to POAS tho. It is so hard waiting.

Implantation still happens between day 7 and 10 so your implantation window was probably between last thursday and tuesday (today).

I didn't get a BFP til d16 and had BFNs on d13 and 14.

Are you on a natural FET cycle?

Best of luck Missy. Fingerscrossed for you,
