If you're looking for someone to blame for your nine months of nausea, then look no further than your parents' other daughter. Yes, your sister's big belly might as well be your pregnancy crystal ball. A recent study shows that those who develop the debilitating "morning sickness condition" known as Hyperemesis Gravidarum (HG) are likely to have sisters who also develop it.

HG is no small thing, either. It's an extreme form of nausea and frequent vomiting that ends up actually endangering the lives of mother and child and forces some women to terminate their pregnancies.

Researchers from UCLA and the University of Southern California traced both the maternal and paternal family histories of women with HG and found not only that the condition could be genetic but that women with sisters who had HG could have a more than 17-fold risk of experiencing the debilitating condition too.

The findings, which were revealed in American Journal of Obstetrics and Gynecology, may scare any women with sisters who went through it. I have known women with HG, and if one of them were my sister, I really might think twice about getting pregnant.

For most of us, morning sickness is either a minor nuisance or nothing at all, but for the women I've known with HG, it truly is debilitating. It's so hard to watch someone you love go through something so painful and hard and even more awful to know that you might go through it yourself.

There is probably nothing that could stop me from having my babies, but it might give me pause to think I could be that ill. I would probably still go through with it and hope beyond hope that this one time, statistics were on my side rather than against me.

Many times as parents we wonder why no one told us about certain things. This is why. Sometimes we think if we told you the truth -- the honest, total truth -- it would terrify you and maybe even stop you from having children. Instead, most of us keep our pregnancy horror stories to ourselves and hope you get off easier.

Would you ever consider not having a baby after someone else's difficult pregnancy?
