I Put A Condom On The Wrong Way Round. Could

I put a condom on the wrong way round. Could a girl still get pregnant from me putting it on the wrong way. I have pre cum, but I didn't cum. Plus I kept it on, I didn't flip it. I just kept it on. I was just worried, my gf said it works both sides. I'm just concerned about it, I know it sounds silly to worry. Just I want to be one hundred percent sure
