Nausea and vomiting can be one of the first signs of pregnancy and usually begins around the 6th week of pregnancy. It can occur at anytime of the day, and for most women it seems to stop after the 12th week of pregnancy.

It's possible that nausea and vomiting during pregnancy might indicate that you're experiencing the normal climb in pregnancy hormones needed for a healthy pregnancy.

Some women with healthy pregnancies never experience morning sickness.
