weight gain and bloat

I'm 11 weeks pregnant with my third baby. I have a little bump but mostly bloat - at that awkward stage where I just feel chubby :/ anyone have a hard time with pregnancy weight gain? I've always been active and very conscious of my weight but this pregnancy I'm hungry all the time and lacking motivation to exercise. Just looking for support. I've gained 5 lbs. it fluctuates based on water/what I eat. I just wish I was one of those super active pregnant women!
