Hey there I lost 12 pounds the first 3 months because of morning sickness too. I also got sick and lost more weight because the lack of food but my morning sickness has decreased and I have been slowly been able to joke down food. As long as u take ur prenatals and give the baby what he/she needs I wouldn't stress over it....8)
Its completely normal. I lost 20 pounds at the beginning and was really worried. My Dr said everything with the baby was fine, she was still growing and so was my stomach. Once the morning sickness dies down, youll start regaining the weight.. And wish youd stop gaining it! Lol
