Af due today but ...

Ka

My af is due today Friday 13th and usually I'll start the night before I haven't started yet and I hope she stays away but this morning I thought I started and I wiped but it was some cm it was enough to get in my panties. Also I keep going to pee constantly and so after I pee I go through the normal of routine of today and I constantly feel like I'm peeing sort of like light pressure down there. Has this happen to any of you and af stayed away?
