My glow predictive ovulation date was November 18th. I had unprotected intercourse on the 24th. I'm two days late on my glow predicted period due date (which has always been right). I had a bleed this morning, was quite a bit with a few clots (sorry tmi), but had nothing since lunch time. What could this have been as I've never experienced this before, once I bleed It's continuous for the 5 days. I'd be grateful for any advice or other people's experiences.
