I'm feeling bummed and vain about stretch marks. I'm 21 weeks with #2 and I've got big stretch marks (3+"/8+cm long) on my inner thighs and hips and a few small ones on the fronts of my thighs and on the bottom half of my belly.

With LO I got one tiny stretch mark (<1cm) sometime in my 41st week.

It feels extra unfair because I'm only up 2 lbs from my pre-pregnancy weight. What gives?

Anyone else have such dissimilar experiences in different pregnancies? Or just want to commiserate?
