Wake me up too Sarah! lol. Feel like I've been doing this forever

Bunnyfeet, I just came across a really old 2WW thread from 2009 lol, and for a 5 day blastie implantation occurs day 2/3. Yay!!!!! You probably have implantation spotting. I read that for a 3 day embie, implantation occurs from day 4. I'm hoping that's why I haven't have any signs yet! haha.
