when they wonder if you’re fat or pregnant?

So I’ve been on bed rest for almost three months now and went out for the first time yesterday to get my nails done. Everyone at the salon didn’t know whether I was pregnant or fat. I’m short and have big hips maybe that doesn’t help. I’m really trying to control my weight but from 12 weeks until now at 14.5 wk I’ve put on 3.5 pounds. Don’t know why the weight is going up so fast! and I’m not allowed to exercise because of my sch. I’ve put on a total of 6 pounds so far and some of it is definitely going to my hips lol. How are you ladies doing?? Any tips for healthy salty or sweet snacks?
