How does the blood in a period have eggs, I can’t see it?

Okay, so here's the thing: your period blood doesn't actually have eggs in it that you can see. That's a super common misunderstanding, and I get why it's confusing!

Your body actually releases an egg before your period starts. It's called ovulation. That egg travels down a tube, and if it doesn't meet sperm, your body doesn't need the special lining it built up in your uterus. So, that lining (which is made of blood and tissue) is what comes out during your period.

The egg itself is super tiny, like, smaller than a poppy seed, and it usually just dissolves if it's not fertilized. So by the time your period rolls around, there isn't a visible egg in the flow. What you're seeing is just that cozy uterine lining saying "bye-bye" for this month. It's totally normal not to see an egg!
