A light period is a menstrual cycle that is shorter and/or lighter than a woman's regular period. Women should familiarize themselves with their menstrual cycle, how many pads or tampons they use, and how long their periods last to quickly detect any changes in their periods.
The answer to this question depends on what is considered a period. Menstruation or a period is the bleeding that occurs when the endometrium is shed 12 to 16 days after ovulation. With this definition of a period, you cannot ovulate while on your period. However, some women experience mid-cycle or ovulatory bleeding (bleeding that occurs around ovulation) and may mistake it for a period. This can be seen in some women who have very irregular cycles, maybe coming once every 3 months or 2-3 times in one month, although it can occur in women with regular cycles as well.
