30 weeks 4 days and have gained so much

I feel like I've gained a shit ton of weight... my pre pregnancy weight was 120lbs, and I was steadily losing .5-1 pound a day from over exercising and never eating. Then when I found out I was pregnant at 9 weeks already, I straightened up and became healthy. I now eat at a good pace, sometimes a little more than I'd like but baby girl is healthy.

Point being, I peeked at the scale... and cried. I'm at my biggest. My normal weight before my eating disorder was 135-145 lbs. I now weigh 187lbs.

The pics below are from a week ago, but most recent.

Am I abnormal? My doctors never say anything at my OB visits about my weight gain, and I'm embarrassed to ask because they don't know about my eating disorder previously. I'm scared. And scared to start exercising because I quit from over exerting myself. I'm on my feet alot with work, and I try to be careful with what I eat.
