Question

Quizplus · Accepted Answer

Nausea or vomiting during pregnancy, also known as morning sickness, occurs in about 80 percent of pregnant women. It is not necessarily related to decreased levels of progesterone, and in fact, high levels of progesterone are thought to contribute to its occurrence. There is no conclusive evidence to suggest that it is associated with an increased risk of miscarriage. While morning sickness is commonly associated with feeling nauseous in the morning, it can occur at any time of the day, and there is no evidence to suggest that taking iron supplements relieves the symptoms.
