I am a week late on my period and I took a hpt monday and it was a bfn, I am on the pill, I did miss one pill though. Me and my husband use the withdrawal method also. I am having cramps like af is coming, I did have a small amount and I mean small amount of blood when I wiped friday (sorry if tmi) it was really light and pink so I figured af was comming that night but now almost a week later nothing at all...Any suguestions?
