Too much weight gain ? 15+6

Ma
I've gained 16 lbs so far. 😕 I'm not doing anything differently than I did pre pregnancy. Idk what to do. I don't drink soda or juice. I drink a ton of water. Eat 3 meals a day. Get plenty of exercise due to working 2 jobs. I don't eat many sweets. 😭
I feel bad about myself when they lecture me on weight gain. My pre pregnant weight was 160 and I'm 5'6" so I started a little overweight.
