Is Pregnancy Possible If Intercourse Was Two Days After Menstruation?

Hello! So I had unprotected sex 6 days ago 2 days after my period. My boyfriend pulled out, but I think he was too late. I'm having some pregnancy symptoms. Like frequent urination, nausea, headaches and my appetite is off and on, && fatigue. I'm having minor cramps it's off and on. I just need to know if I can possibly be pregnant.
