Can I get my period 14 days early

Yes, you can get your period 14 days early, especially if you started having periods within the last couple of years.

Your cycle counts from the first day of one period to the first day of the next one. When you are new to having periods, your brain and ovaries are still figuring out how to talk to each other, and in the first couple of years most cycles do not release an egg yet, which makes dates jump around a lot. One cycle might be 35 days and the next might only be 21 days, so it can feel like it showed up totally out of nowhere.

For the first couple of years cycles are often uneven, usually somewhere around 20 to 45 days from the start of one period to the start of the next, and one cycle that's shorter or longer than the last isn't on its own a reason to worry. Stress can make a period late too. Tell a grown-up if your periods keep coming more than 45 days apart, 3 months go by with no period once they've started, or they keep coming less than about 3 weeks apart.

Also, if this early bleeding means your period came twice in a month or stopped and started again, keep an eye on your flow: most people bleed for 3 to 7 days, and a first period can be much shorter and lighter. Tell a grown-up if you need a new pad or tampon every 1 to 2 hours, your period lasts more than 7 days, you pass clots bigger than about 2.5 cm, blood leaks through to your clothes or bed, you miss normal things because of your period, or you feel tired or out of breath a lot.

If you want to keep track of these random dates so you can see your own pattern, you can log when it starts and ends in the Soso app.
