We also talk about secondary sexual characteristics, and why everyone grows at their own pace (and that’s totally normal).

In this video, we explore the menstrual cycle — a natural biological process that marks the beginning of reproductive maturity in girls. We’ll understand what it is, why it happens, how often it occurs, and how to take care of your health and hygiene during menstruation. We also address the myths and taboos that often surround periods, and why it’s important to replace misinformation with facts, empathy, and awareness.
