Could I be pregnant?

Hello! I need some advice from whoever is willing to give it. Around my ovulation time, my fiancé and I had unprotected sex multiple days but practiced the pullout method (which I know isn't 100%). Then I had unprotected sex with him again the day I was supposed to start my period but he did not pull out. I am now almost 2 days late with my period. Do you think there's a high chance in pregnant? I'm still feeling cramps and normal period symptoms.
