23 weeks pregnant and already gained 20 pounds

Brittany

Hi! This is my first pregnancy. I started out at 157 pounds and I'm 5'7. Weighed myself today and I'm at 177. Is this normal to gain this much already? I feel like I've gotten a little chunky in the face but I'm really all belly. How much have you guys gained? I have a doc appt next week so I plan on asking if I'm gaining too much
