What Causes A Light Period?

Every woman experiences their "time of the month" differently, and there are various factors that affect menstrual flow. Some women may have difficulty with heavy flows, while others breeze through their period with no problems whatsoever. Everyone has their own "normal" regardless of the duration or amount of blood flow. Women have to pay close attention to the changes in their cycle to recognize potential health issues. A normal period typically lasts from two to seven days. Most women have consistent periods with the same amount of days and flow, but some women's cycles are not as predictable. Spotting or light bleeding for less than two days or missing one or more periods could be an indication of one of the health conditions below.

Pregnancy

The menstrual cycle ceases during pregnancy and doesn't return until after the birth of the child. Women typically do not have their periods during this nine-month period because the uterine lining is needed to nourish and provide a home for the growing fetus. Almost thirty percent of women will have some light bleeding or spotting in their first trimester. This can be caused by different issues, such as cervical irritation, infection, or a possible miscarriage. 

Implantation bleeding is a common cause of spotting or a light period. It happens when the fertilized egg becomes embedded in the wall of the uterus. This usually happens around the time of the next expected period, confusing many women. Implantation bleeding is usually much lighter than a normal period, and the color may be pink or dark brown. Some light bleeding in the early stages of pregnancy is considered normal. However, you should inform your doctor if it doesn't go away or becomes heavier, especially if it's accompanied by painful cramping or back pain.
