I had my routine OB appt today. The doctor came in and asked if my diet was normal, in which I answered, yes. I don't eat tons, but I do eat. May e not as muxh as I should. Anyway, he did the routine exam. Measured my uterus and listened to her heart beat. All were perfect. He said for me to come back in 2 weeks for an ultrasound to check on her growth. I asked why and he said that I haven't gained any weight, that in fact I am still down 4lbs from the first time I came in. He said by now he would like to see at least a 10lb gain. I am slightly worried for my little girl. Should I be concerned?
