I'm three days late and there haven't really been any signs of AF. After sex this morning I went to the restroom and there was some light pink spotting so I thought AF was coming. After that one time the spotting went away. I've put in a Tampon in, nothing. I checked with a finger, nothing. No cramping or anything. I know it's way too late for implantation but is spotting after sex normal? When I spot before a period it's always brick red and gets heavier and heavier and AF comes about 4 or 5 hours later so I don't think it's the witch. Any feedback would be great!
