I am 19 wks pregnant and I was banded in 2007. As of today I have lost 20lbs since the begining of my pregnancy! I have not had an unfill and kinda reluctant to get one. At my last doctors appt. my dr. told me I am not getting enough calories in and I'm starting to get scared! I dont want anything to effect the health of myself or the baby. So far they say the baby is growing fine which is great! But, does anybody have any suggestions on what I should eat or If I should get an unfill or not?

I have lost 20lbs since i have been pregnant. I am now in my second trimester. I am 40lbs from my goal weight and I am vomitting sometimes but not all the time.
