I didn't get mines until after I had my daughter

It's possible. I've seen people here say it's hereditary but I've never seen it anywhere else. As long as your body stretches, it's possible to get stretch marks.

It's possible! :). as for the hereditary thing.. my mom got destroyed with stretch marks with my older brother who was her first and my son is now 13 days old(my first) and I walked away with like maybe 4 stretch marks and they are on my hips and tops of my thighs. and I'm pretty sure I got those because I gained a little to much weight.

I didn't get any stretch marks until about 35 weeks.

Possible.. Stretch marks are hereditary though
