(BPT) - The big news that a baby is on the way is a time for celebration, excitement and planning. Many couples choose to keep this information quiet for the first couple of months, so they can celebrate the upcoming change in their life together. But sometimes, morning sickness for the mom-to-be can let the news out of the bag earlier than intended.

Morning sickness – pregnancy-related nausea – is very common, especially during the first trimester. However, the problem isn’t the same for every woman, as the nausea can occur at any time of day or night (not just in the morning) and some women experience it throughout their pregnancy. For some women, it’s a minor annoyance. For others, it can become a serious issue. No one is sure exactly what causes it, but hormonal changes that take place during pregnancy probably play a role.

Morning sickness relief can be complicated, too, since many women try to avoid taking medications during pregnancy. And what works for one woman, may not be as effective for another.
