Feeling huge

Ok, I know I’m pregnant and I know it’s beautiful.. but I am a petite person, always have been, I didn’t get huge with my daughter but I’m about 18w now and already gained 12lb and my stomach looks like it did when I was like 27 weeks with my daughter!! I keep seeing all these posts about not gaining or having a small bump but I feel totally opposite.. HUGE! I eat relatively healthy and treat myself to things I want as always.. nothing crazy. Anyone else?!
