Babycenter.com listed a few reasons why women tend to have severe morning sickness. I found it interesting because of what I have been going through. The three reasons below I found to be of interest specifically to me. The first two because they are true, and the third because I do have a little hope! :)
• You have a history of motion sickness.
• You have a history of migraine headaches.
• You're carrying a girl. One study found that women with severe nausea and vomiting were 50 percent more likely to be carrying a girl.
