Im 10/11 dpo I tested earlier got bfn little while after thought started what I thpught to be af 1 week early. Got af like cramps put tampon in because thought im out just been loo just now theres nothing on it only a little bit looks like dry blood from earlier im only getting a little blood when I wipe. Still cramping slightly. So confused right now is it af or inplantation bleeding ? Would it be af a whole week early ?
