So I'm 25 weeks and 1 day. I'm having twins and lost 15+ lbs in the first trimester. Just gaining that back and now losing it again. The sickness is real!! Uggghhh The babies are 1lb 9oz and 1lb 7oz so it's not affecting them they are thriving. I guess I should be happy about not gaining weight just crazy with carrying twins I was terrified I would gain alot. As long as they gain that's all that matters.
