Understanding Healthy Weight Gain During Pregnancy: A Doctor's Perspective

Question
I read where you told a women that it was okay that had low weight gain because she stated that she was overweight to begin with. I am not. I am 32 weeks,5'9".My pre-pregnancy weight was 169 and I have only gained 6 pounds.I am very concerned especially since I am eating normally and not at all sick.

Answer
That is certainly not enough weight under most circumstances.
Have you been seeing a Dr.?  What does he/she say?  I have seen/heard of women gaining very little weight and having healthy babies.
You should talk to your Dr. and possibly have an ultrasound.
Good luck and Congrats!
