Could I possibly be pregnant

FH

I had sex with my bf last week

Could I possibly be pregnant I used the condom with him but he put it on the wrong way and flipped it the other side he says he didn’t pre cum in it while he flipped it the other way or cum. But after we was done he actually cum in the condom a liltle bit and there wasn’t any holes or nothing in the condom could I get pregnant or no ??? And I did this on a wed when it had a green fertility sign
