Ttc #3 after the merina

We tee ttc #3 after the merina. It was removes sept. 19th... ovilation dates were oct 5,6th. They were confirmed with ovulation strips. I was due to start af yesterday. No signs of it starting. Today I have been a little crampy but nothing big. And now I have a light discharge after I use the bathroom with a little dark pink blood. Nothing that goes on the liner. Only when I wipe.

Anyine know what implantation blood looks like? Oh and first responce pt was negative yesterday! Ideas??
