Hate doctors!

I had my 32 week appointment yesterday and my doctor really made me mad! She basically told me I don't eat enough because I've only gained 15 pounds so far. First of all, I eat all the time and not junk. I eat plenty of protein and fruits and veggies. Each appointment my fundal height is exactly what it should be and all ultrasounds have shown the baby measures a week ahead. Latest ultrasound was at 27 weeks. I am a petite person who has always been thin. There is no concern over the health of my baby so why bother me with saying I don't eat enough. Not everyone gains the same amount of weight. If my baby is healthy then leave me alone!!!
