So this morning round 9:30 I went pee and wiped, there was blood...I thought AF had arrived..So I put a tampon in and went to Walmart... About 1:30 I go to the bathroom again, took it out. There was hardly anything on it... and it's like I'm not bleeding anymore..and according to glow I was supposed to have gotten my period 4/20. Any thoughts of what's going on?
