Morning sickness is a condition that affects somewhere around 50% to 90% of pregnant women. Morning sickness typically will start between the 4th and 6th weeks of pregnancy. There are many factors that can contribute to causing morning sickness. Some causes may be:
- rapid hormone changes.
- a tricky stomach. That is, your gastrointestinal tract may be particularly sensitive.
- enhanced sense of smell and sensitivity to odors.
it is quite normal for morning sickness to stop and start anytime during pregnancy, sometimes very suddenly. While some women are lucky enough to have their morning sickness subside as early as the 12th week, generally, morning sickness stops between the 14th and 16th week of pregnancy. For some women, morning sickness will only occur in short 2-3 day bursts during the first trimester, with long stretches in between with no morning sickness.
Also, a lack of morning sickness is not always a bad thing. Morning sickness can also vary from pregnancy to pregnancy. Having no morning sickness in one pregnancy does not guarantee that you won’t have any signs of morning sickness in future pregnancies and vice versa; if your morning sickness suddenly stops during one pregnancy, it may taper off during a future one.
