Heavy Bleed

Hi everyone, I need so help. I have been ttc for the last 5 months. This month I felt myself ovulate BD every night and since have felt like I've been having odd symptom. I have had sore boobs, fatigue, increased appetite and even odd cramps in my stomach, I was royally sure that this was our month.

This morning will be 9 days before my AF is due and I'm always super regular. every 33rd day in the evening.... and yet I started to bleed this morning. It even went through my jeans (TMI).

is this a really bad sign? x
