Stretch marks second pregnancy but not first?

So I was very happy to not get stretch marks my first pregnancy. My son came out huge and belly was big for my size. I didnt use the creams or oils really, because I was told it was hereditary and none of the women in my family have them and they've all had 3+ kids. So has anyone gotten them their second pregnancy after not getting them with their first? I feel like my belly is growing so much faster now so I'm a little nervous.
