The female body is a bit of an enigma… even to us women, to be completely honest. The menstrual cycle, that marvellously affords us the power to create life, is also, to put it mildly, a massively complex biological process. Contrary to popular belief, menstruation and its effects don’t just mess with us 5 days a month, people. It’s a process that lasts practically our entire lives.

And here to break it down for all men and women alike, is a tell-all video by Glamour Magazine. This 2-minute video throws a fresh bucket of light on the ambiguous blur of ups and downs that make up a woman’s 28-day menstrual cycle.

At best, this video helped you understand your (or a loved one’s) experience a little more holistically. At worst, you’re plotting to make fun of someone’s mood swings or acne using this info. Either way, you definitely know more than you did 2 minutes ago.
