ok, this was so many months ago so i can't really remember his exact explanation but the idea is that morning sickness is an indication that the the pregnancy is progressing well, pregnancy hormones,placenta, blood flow, etc good....not sure how true this is but i suppose that's why amandamoo is asking about "feeling pregnant" as she said she heard somewhere that morning sickness indicates a healthy pregnancy.
anyway not sure how true but found an article:

Nausea and Vomiting in Early Pregnancy: Its Role in Placental Development
The etiology of morning sickness, which is experienced in early pregnancy by up to 70% of pregnant women, has been linked to increased levels of thyroxine and placental hCG. Morning sickness has been associated with decreased risk of miscarriage, preterm birth, low birth weight, and perinatal death. Based on data from the literature a functional role for morning sickness in stimulating early placental growth is postulated.7
Nausea and vomiting during early pregnancy induces a reduction in maternal energy intake causing lower levels of anabolic hormones, insulin, and insulin growth factor-1 (IGF-1). The lower levels of these anabolic hormones decreases anabolic maternal synthesis and fat deposition, favoring nutrients to be used more for the developing placenta. There is also data in the literature that suggests that women who are underweight will experience less severe symptoms of morning sickness compared to women with a normal pre-pregnancy body mass index. It is postulated that in women that are underweight the increase in energy intake will result in elevated insulin levels leading to impaired placental development and therefore reduced production of placental hCG and thyroxine and less nausea and vomiting.
amandamoo: best wishes with your pregnancy, if you are concerned, ask your doc if not just enjoy it! i think everyone will have a different pregnancy story, bad morning sickness, no morning sickness....most important is mummy and baby are healthy!
