penis inside vagina for about a minute at a time about an inch in

so the other day my boyfriend and i were messing around. both of us were naked and i was on him but he wasnt in me. then we wanted to try sex so he went in me but it hurt so he stopped then we tried me on top each time we tried it was about an inch or two in my vagina and then it hurt so we stopped completly but we tried atleast four times and he did have a little pre cum he said. is there any ways i could be pregnant from this? any help would be greatly appreciated thanks
