My classmate accidentally came in my pussy... I hope I don't get pregnant.

We had sex with my classmate and didn't use a condom because he promised me that he was in control of everything and would be able to get his dick out of my pussy in time...but unfortunately he was too horny that he didn't have time...and he came right inside me..Now I'm afraid I might get pregnant... i advice everyone! please use condoms if you are not sure about your sex partner
