Question for those with significant stretch marks

Michele

So I know there’s no way to prevent them but I’m curious about when they showed up for those who have/had significant marks. I have none yet at 30 weeks, but I have old ones on my thighs from high school and some newer ones on my hips/bum from weight gain about 12-18 months ago. None on my belly yet though! I’m hoping desperately that if they haven’t shown up by now they won’t ever but I’m sure I’m being naive....
