Normal bleeding?

Ladies...

I just found out I'm pregnant yesterday estimated due in July. ❤

I really don't know how far along I am. My last period was September 4th. But I think I ovulated super late and conceived on October 7th, which would make me about 4 weeks.

DH and I had intercourse yesterday morning and today I started bleeding. Started out brown, then turned a more bright red. I have a small amount of cramping but not severe. Could the bleeding be from sex?

Has this happened to anyone else, and when did it stop?
