I'm not sure why this specifically popped into my head. But I have made it 40+ weeks without any stretch marks. Is it possible that they will show up after I have had Rosalie and my skin has gone back to its normal self? I hope that makes sense.
It's possible some will show up but you could get lucky. I didn't get any on my stomach with my first and made it to 37 weeks with my second without them, and they're pretty much clear
