TMI WARNING:
Okay so on 1/07/16 ( 9 dpo) I had dark brown Mucousy discharge, (never experienced this before) that only lasted a couple of hours and only saw it when I wiped. Nothing on 1/08/16 then on 1/09/16 & 1/10/16 (11&12 dpo) it was light brown with some reddish tinge, as shown below, still only saw when I wiped. On 1/11/16 (13dpo) I wiped and it looked like this: (shown below) and Today 1/12/16 It has completely stopped. AF is due today and it was a no show as well. Is this implantation bleeding? I took a Prego Test today and it was negative😩 did I test too early? Help!!!!
