Stretch marks by 30 weeks

I was wondering how all of you beautiful mamas are doing as far as stretch marks. I know there isn't much you can do to prevent them, as I have heard a lot of it has to do with genetics. interestingly enough, a few people I know actually got their stretch marks after delivering the baby and not during the actual pregnancy. Let me know your routine if you are preventing them. I haven't gotten any yet and it feels like my skin didn't get to its maximum tightness yet and there is still room for it to stretch but I guess it could happen any day now. Either way I get so excited to see my belly grow and get bigger it just means I am getting closer to meeting my little boy ❤
