The period after delivery is often considered the “fourth trimester” and can last between 30 days and three months. There are many changes that occur in a woman’s body during this time including hormone fluctuations where estrogen levels drop approximately 300%. This hormonal shift generally takes an average of 10 days to balance out. With the hormone changes that occur post-pregnancy coupled with sleep deprivation, adapting to the demands of a newborn, and fulfilling countless other responsibilities, it is normal for a new mom or even a seasoned mom to have multiple changes in mood over the course of a day. After the much anticipated arrival of the new baby and the excitement of birth, it may come as a surprise for new moms to experience emotions such as sadness and anxiety.
