So, I'm 12 DPO and my AF is due Sunday 11/20 and my temp dropped yesterday, so I been counting myself out, but I was going to the bathroom yesterday afternoon and when I wiped there was light pink blood, my first thought was "AF came early" but I wiped again nothing, and I checked my cervix it was high and soft and I had a mixture of egg white and creamy cm..... what do you guys think? I'm 12 DPO and by boobs still hurt and temp went back up.... so you think it's AF??? OMG!! Now my mind is blown... I mean if it was implantation I should test in a few days... like Saturday..... right....
Here is my chart:
