Ok ladies, i will be 18 weeks tomorrow and have only gained 3 lbs. since I became pregnant. This is my second pregnancy but i swear i gained a lot more by this stage last time. I am scared that something might be wrong with the baby. I have not had any morning sickness, or any change in my diet. I have actually been eating healthier than what I was pre-pregnancy. I dont know if I should be worried about this or not?
