Factors That Can Affect Your Period

10. Pregnancy

Pregnancy puts a stop to your period during the pregnancy and for some time afterward. While some women do experience light spotting throughout gestation, bleeding is a sign to contact your doctor. Once you give birth, your body will spend a few weeks expelling the uterine lining that acted as a home for your baby for the past nine months. After that, your normal period may not resume for some time.

Factors that dictate when your period returns [HealthDirect] include whether or not you breastfeed and how often, as well as your body reacts to the normal hormonal changes of pregnancy and giving birth.
