Causes of a light period The following factors can cause periods to be lighter than usual: Age Period flow can vary throughout a person's lifetime. Early periods are usually lighter and may only involve spotting. They become more regular when a person is in their 20s and 30s. In their late 30s and 40s, people may develop heavier and shorter periods. They may skip months without periods, and have a heavier period later. Periods often then become lighter and more irregular during perimenopause. A lack of ovulation Sometimes a woman has irregular periods because her body does not release an egg, which is known as anovulation. This can lead to lighter or irregular periods. Being underweight People who are underweight may notice their periods are very light or stop altogether. This change happens because their levels of body fat drop so low that they do not ovulate regularly. Exercising too much is another cause of light or absent periods and may also be linked to being underweight. Pregnancy During pregnancy, a person's periods will usually stop completely. However, people may mistake implantation bleeding for a light period. Implantation bleeding is an early sign of pregnancy. When someone is sexually active and does not usually have light periods, they may wish to take a pregnancy test. Medical conditions Medical conditions that affect hormones in the body, such as polycystic ovary syndrome (PCOS) and thyroid-related conditions, can affect a person's menstrual cycle. Stress Periods of stress can affect the body's hormonal balances, which can interrupt the regular menstrual cycle.
