When did you get your BFP after 5 day embryo transfer?

Hi ladies,

I’m currently on my 3rd day past 5 day transfer. And was wondering when implantation happens? And when did you test to get your BFP? I transferred only 1 frozen blastocyst (5 day embryo).

This is my first FET im just getting use to the terms and language. Bare with me lol

Thank you!
