Some people don't ever really get over the sick feeling.
Mine ended at about 20weeks and has been on and off til now that I'm 34wks2days.
Sickness is an indication of a healthy baby. Some women are sick the whole pregnancy.
It's Normal I am nearing the end of my second trimester and still get nauseous every now and again. Especially if I don't eat enough, which is hard to tell since my body doesn't always get hungry when it wants me to eat...
Unless you feel like you have a bug or something its okay to still be sick. I was sick the most during my second trimester!
