In this lesson, we break down the menstrual cycle in clear, simple biology. We walk through what the cycle is, why bleeding happens, how hormones shift across each phase, and what cramps actually are. We also talk about what period blood is made of, what different blood colors can mean, and why symptoms like fatigue, mood changes, and cravings show up for so many people.

Then we head into our Biology Lab and test a period cramp simulator on Asa. We compare what the simulator feels like at different levels, talk honestly about how disruptive cramps can be in daily life, and reflect on why menstrual pain is so often minimized. If you have ever felt confused, dismissed, or embarrassed about periods, we are here to make it make sense and make it easier to talk about.

Part two continues the lesson with the cultural side of menstruation, plus a true or false quiz that brings it all together.
