Barely gaining any weight

Sy

My starting weight was 155lb, I lost 5lbs in the first trimester and I’m now 18 weeks and since week 13 I’ve only gained 3 pounds, so I’m sitting at 153 right now.

My bmi pre pregnancy was considered overweight, but it’s making me really worried and making me think something is wrong?!

Anyone else not gaining as much as they thought they would be by now??
