Hormonal changes that happen during pregnancy

All of us have hormones in our bodies.

These are chemicals that help to regulate how our bodies function and they circulate in our blood stream. They carry messages to and from various parts of the body.

Your hormones are mainly triggered when your body needs to adjust to certain changes physiologically. These triggers may include changes in metabolism, behavior and also emotional changes.

When you get pregnant, or when a lady gets pregnant, there are many physiological changes that occur in the body.

This happens as a result of adjustments in the endocrine system as the body prepares to accommodate the new developing unborn child.
