What happens with cycles over 35 days?

Okay so it's super normal for cycles to be all over the place when you're first starting your period, like they can be as short as 20 days or as long as 45 days and still be totally normal. In fact, in the first two years, the average is actually around 32 days, so 35 days is just fine.

Your body is just figuring things out, and most of your early cycles won't even release an egg, which is why they can be a bit unpredictable. It's all part of growing up and your body changing.

But if your periods consistently keep running longer than 45 days, or if you go 3 months or more without a period, then it's worth talking to a trusted grown-up. They can help you figure out if you need to chat with a doctor just to make sure everything's good.
