Implantation bleeding ?

Hailey

Hello everyone, so recently I had sex for the first time and it was on my last ovulation day, the guy I did it with had a condom on and pulled out however the day after when I went to use the restroom I had yellowish discharge with blood. It has now been about 5 days and my stomach still feels funny and I’m not sure what to do does anyone know if the discharge was ovulation or implantation bleeding?
