Bleeding/Ovulation

I was fertile this past week from last saturday until yesterday. I ovulated friday. Started bleeding last night. It's pretty smooth but has been bright red every time i wipe and i've gotten light cramps. Had raw sex last Tuesday but used the pull out method and have used condoms since. This has never happened before???? Is this normal?? It seems a bit soon for implantation bleeding. My period isn't due for 2 more weeks.
