Nausea During Pregnancy

This is my sixth pregnancy, and I’ve had four live births so far. I know every pregnancy is different. I already have 1 girl and 3 boys, and now I’m about 9 weeks along. I’ve been feeling super hungry, but after eating a full meal, I get nauseous. On the other hand, if I don’t eat enough during the day, I also feel nauseous. The only thing that helps sometimes is ginger ale. Does anyone have advice on how to manage this? Also, just for fun, what do you think the gender might be? I hardly had any nausea with my boys, but I did with my daughter. With this pregnancy, the nausea seems to be getting worse each week.
