SoReady, I think any kind of nausea is considered MS, some women don't ever vomit but feel nauseas. Everyone says I am having a girl because I have been so sick this time around. With my boys I was sick but not this bad. I have been vomiting at least twice a day since the day I was 6 weeks along and still am even with medicine. So I actually looked up morning sickness being worse with girls, and there have been studies done that proves it, it's not just an old wives tale! Now obviously women pregnant with boys can get horribly sick and all pregnancies are different but it has been proven that female fetuses produce more hcg, which can lead to worse MS. I have also had a lot of symptoms during the past 10 weeks that I didn't have with my boys until later one, like cramping, acne, dizziness, heartburn, backaches, so I am praying it means a different gender! Good luck to everyone getting ultrasounds soon, I am having my NT screening in 2 weeks and just hoping I get a good nub shot.
