What happens when your period doesn't start?

Okay so if your period doesn't start when you expect it to, it's called a delayed or missed period, and it's super common, especially when you're just starting out.

Your first few years of periods can be totally random, like a surprise party you didn't RSVP to. Your body is still figuring out how to do this whole period thing, and it can take a while to get into a regular rhythm. It's totally normal for periods to be a bit all over the place at first. Stress can also mess with your cycle, so can changes in your eating or sleeping habits, or if you're super active with sports. Basically, your body is like, "Whoa, hold on a sec!" and pauses the period for a bit.

If you've had periods for a while and then one just... doesn't show up, it's still usually nothing to worry about. Keep tracking your cycle in the Soso app to see if it shows up a little later, or if your next one comes when it's supposed to. If you're getting a lot of delayed or missed periods, or you're feeling really worried, it's always a good idea to chat with a trusted grown-up or a doctor, just to make sure everything's okay.
