I'm right there with you! I'm 19+ and still sick. I got textbook sickness with my first two, both girls, and the last was also a boy (this is the 4th and a boy) and was sick all the way through. I don't think I make boys well! Haha, or the boys don't let me be well... there's a bad pun in there somewhere, lol.

Just try and eat small things whenever you can, snack a lot, drink a lot, don't neglect yourself! They're little scavangers and are taking everything they need.
