Okay so I OV on the 13/14 of this month was suppose to get AF on the 23rd and still haven't gotten it. Took a Pregancy Test today Got a BFN but just a while ago went to the bathroom and have some light pinkish on the toilet paper. Couldn't it be implantion bleeding? Little cramping just started an hour before. But nothing major like I usually get when I start my period. Can anyone help please?
