NBC News – (NBC News) Morning sickness, the nausea that accompanies many pregnancies, can be a pain but new research finds it's really a good thing.
Scientists say it's a good sign the pregnancy is going well.
Researchers at the National Institutes of Health studied nearly 800 pregnant women.
All had previously endured at least one miscarriage.
Those who had nausea and vomiting were much less likely to lose their current pregnancy.
"This can help sort of provide some reassurance that you know at the end of the day it really indicates that they have a healthy pregnancy," says the NIH's Dr. Stefanie Hinkle.
Of course many pregnant women have no symptoms and feel great. Doctors say those lucky ladies should not be troubled by this latest study.
