Bleeding?

My period started on the 30th & ended on the 3rd. Two days later my husband & I had sex. Afterwards I started bleeding a lot. Like period amount. I could understand if it was old blood but this was red blood not brown.

& Today is my first day of ovulation. I spotted a little in my underwear & then later I noticed a little bit of blood in my EWCM.

Is this normal or could something else be going on? I have never experienced this before.
