Question....

2-4 days after implantation bleeding it states you can test. Also it states you can test 6 days before your missed period, which if I am correct would be exactly at my 2 week pregnant marker... Should I just wait until the 2 week marker? Or should I try in two days, but not get disappointed as it could just be too soon? I just don't want another let down if this is not implantation bleeding I am expieriencing. Ps- Not wanting to tell my husband yet due to if I am pregnant, I'd like to announce it to him on Christmas? Yay or nay? :) Thanks! Xo.
