HELP I’m freaking out

I had unprotected sex about 3 days ago and I’ve been cramping bad every since ! Today I started spotting ik it can’t be implantation so soon but could it mean I am ovulating and could that mean I can get pregnant since he didn’t pull out 🤦🏼‍♀️ has anyone had cramping and light bleeding 3 days after sex and was pregnant??!! (Here’s the pic it was slightly pink but earlier when I wiped there was also some very like spotting)
