26 week weight gain...up 24 lbs w/ twins

I'm currently 26 weeks pregnant with twins and up 24 lb. I was pretty excited about this because my first trimester I lost weight and I've been trying to play catch-up eating as much protein as possible.

When I ask my doctor if this is good he said it was a little high and he would expect 16 lb for twins and 8 lb for regular pregnancy. 🤔

I just started seeing this doctor at 19 weeks and I'm wondering if maybe there was confusion between my starting pregnancy weight and my weight when I started seeing him. Because his recommendation just sounded really low to me. I also haven't gotten the warm fuzzies from this doctor like I did my last and wondering if it's just me being too sensitive. Just looking for reassurance that I'm not totally off track here.

Also, my pre-pregnancy weight is considered within the normal range.
