Stretch Marks?

So I had a child before wls, and basically had horrific stretch marks with him.  I'm talking 1-2 inch wide stretch marks covering my hips, belly and tops of my thighs.  I was HUGE with him!  I was as wide around as I was tall lol.  So now that I'm down close to goal, I have this deflated ugly tummy with stretch marks.  Am I destined to get them again, or is it possible my skins is loose enough that baby will just take up the extra baggy space?  It doesn't matter either way but I've just been curious.  :)

I have zero new stretch with this pregnancy.
But I only gained 20 lbs and last time I had twins (pre-WLS). The stretch marks on my belly from my last pregnancy are barely visible, I've been thrilled with this post-WLS pregnancy.

I got hugely round this past pregnancy! I did not have a lot of saggy skin post op but I the skin was pulled really tight! I did not get any new stretch marks though.

I have not gotten too many with this pregnancy. I am having twins too lol
