I'm 17 1/2 weeks along now and stillllllllllll have morning sickness. I hate when I'm nauseated in first tri and someone who's so far along says that. hahaha. But it's true - and not common. I had nausea for about 24 weeks when pregnant with my daughter, but it was gone by the end of the first trimester when I was pregnant with my sons. 8-9 weeks is supposed to be the peak, but my peak week has varied with all of my pregnancies. I've had five pregnancies, my and my worst weeks were 8, 5, 16, 6 and 14.
