I didn't eat but maybe 1 meal a day until 16 weeks and my baby measures 21 weeks and I'm only 19 so he is healthy:)
Dont worry about the way you r sleepibg just sleep how ur comfortable your body will tell u when u cant anymore
Prenatals are important at the early weeks. I barely ate for 2 weeks straight in my earliest weeks with my morning sickness. Its normal to lose weight in the first trimester if you're pretty sicky. Discuss with your doctor what's normal for you and your body
I believe that as long as your small meals are rich in nutrients and you're taking prenatal vitamins your little baby will be fine
