Last month of pregnancy with no weight gain??

Kristen

I’m 37 weeks pregnant with my second baby girl, and have only gained 15 lbs my entire pregnancy. That being said, I have not gained anything in the past six weeks and have actually lost two pounds. I have a “sizing ultrasound” next week to make sure that she is growing okay, but my doctor said she wasn’t super concerned since she’s still been moving normal and has plenty of fluid in there. But I can’t help but be a little worried since this is my second baby and I feel like I should be gaining weight? I gained a total of like 21 pounds my entire first pregnancy and my first daughter was 8 lbs 5 oz when she was born. Has anyone else dealt with something similar in their second pregnancy? Is this normal??
