If you got all the pantang larang... all food that are cold are not advisable..
Folic acid and milk definately will help..
My wife only take folic acid and drink milk as during early stage of pregnancy her morning sickness is quite severe..
But do need to keep track of the weight. my wife kena scold by nurse a couple of time as she gain weight too fast.. hehe..
Anyway congratulation and welcome to club..
