How much have you gained?

I'm 18 weeks with my first baby and have gained 15 pounds thus far. It must be all belly/boobs bc my husband and I don't notice any other changes. I sure don't feel like I've put on that much weight but I was underweight to begin with so needed to gain a couple pounds anyway.
How much weight have you mama's put on so far? This is not a post to judge, I'm just curious how everyone else is coming along! Thanks for sharing!
