Lost Weight?

Me

Anyone having issues with gaining weight? I’m 5’4” and started out at 139 lbs. Last appointment I was 152 lbs. Today at 32+6, when the doctors office weighed me I was 145 lbs. I struggled to gain weight throughout my first pregnancy and my baby was born 5 lbs 14 oz at 41+6. This baby was measuring 2 weeks behind at our ultrasound 2 weeks ago. I’ve been drinking Ensure on top of trying to eat more but I really don’t have much of an appetite. I’m really worried about how tiny my baby will be. I don’t want him to struggle because of me
