So today there was nothing when I went to the bathroom in school but now there’s a little so I am wondering if it was like taking a break or something

Yes, periods can totally stop and start again, especially when you are just starting out.

Flow is almost never steady from start to finish. It is super common for your period to seem like it completely vanished while you were sitting in class, and then suddenly show back up a few hours later. When you are sitting down or moving around differently, blood can collect a bit before making its way out, or your body might just be shedding the lining in little waves. It literally feels like your period took an afternoon nap and then woke back up.

Here is what you can do about it right now:

• Keep wearing a pad or panty liner for an extra day even if you think you are totally done, just in case of sneak attacks.
• Pack a couple of backup supplies in your school bag so you never have to panic in the bathroom.
• Change your pad every 4 to 6 hours, sooner on heavy days.

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.

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.
