A couple concerns

Alayna • Currently pregnant with twins! Mommy of two angels, McKenna Copeland; 1/15/14 & Gabriel Ryker 4/19/15
So I'm almost 6 months pregnant with twins and I had a couple questions. My next doctor's appt. isn't for another week and I don't think any of my concerns are too serious so I figured I'd just make a post lol! Anyway, I noticed that my belly button hasn't popped out yet, I'm pretty small still for being 24 weeks with twins, and I'm carry kind of high. I was just wondering if anyone has similar experiences? (:
