This video reviews the stages of the menstrual cycle and talks about how it can vary in terms of how long it lasts and how often it occurs, especially when girls first get their periods - which is totally normal. It talks about how the fertile period is not always in the middle of a cycle, and that cycles vary from 21 to 50 days (or even shorter or longer) versus the 28-day cycle that is often talked about. The video points out how fluctuations in the menstrual cycle can make it difficult to predict when you are less likely to get pregnant, increasing the risk of unintended pregnancy. Using male or female condoms is always the best way to prevent unintended pregnancy and STIs, including HIV. The video emphasizes the importance of getting to know your own cycle to know when to expect your period and be ready for it.
