When Does Morning Sickness Start?

Morning sickness varies from woman to woman and pregnancy to pregnancy. However, most women start to feel green around the gills about halfway through the first trimester, between weeks six and eight. "It's almost unheard-of to get morning sickness prior to week six, and generally, it's not going to start after week 14," says Michele Hakakha, M.D., FACOG, an ob-gyn in Beverly Hills and author of Expecting 411. The exception: Late in pregnancy, your baby may push down on your stomach and intestines, causing nausea. Many of the same strategies you use for standard morning sickness can also help with this late-pregnancy nausea. Morning sickness is neither a good or bad "symptom" and has no bearing on how healthy a pregnancy is....however, severe weight loss as a result of illness may be dangerous to a developing fetus and should be treated either at home or in a hospital setting, says Marra Francis, M.D., an obstetrician-gynecologist in The Woodlands, Texas. 

When Does Morning Sickness End?

Most women start to feel much better by week 16. Only a small number (around 10 percent of moms-to-be) experience nausea and vomiting all pregnancy long. If your morning sickness isn't letting up, let your doctor know. There are certain medications that can help you feel better, like ginger candy or a vitamin B6 supplement. If your morning sickness stops abruptly during the first trimester, talk to your doctor. But keep in mind: Although your nausea has subsided, that doesn't necessarily mean something is wrong with your pregnancy. For some women nausea is a symptom that they feel every day.  For others, nausea is intermittent.
