Good or bad sign?

So according to Glow AF is due is 5 days though my OD is 1day earlier than Glow predicted.. I’ve just been to the bathroom and when I wiped I found what was like a clump of light red cm.. I’ve never had this before AF is due, I always get AF full force from first thing in the morning.. Any ideas what it might be? Also since OD day passed I’ve had nausea and I broke out with spots which only ever happens about a day or 2 before AF...

Any suggestions or advice would be great ❤️
