AF ⁉️

Jen
I started AF on the 23, which is what glow predicted. I'm just confused. AF for me lasts 4-5 days and I don't start slowing down and spotting til the last day of AF. Well on day 2(which was yesterday) by the end of the day I started spotting and I'm still spotting today. This is not normal for me. What could be going on?
