When a girl gets her first period, she may feel some liquid come out of her vagina. A girl might have a difficult time realizing that liquid is coming out of her vagina at first. She will probably first see a red or reddish-brown liquid stain on her panties. A girl's first period can be a surprise. The period will not come out all at once, so you will have time to get ready. If you are at school, you can ask the school nurse for help. The nurse can provide sanitary supplies for you.
Some girls will let their buddies know that they have had their first period; others won’t, telling their mom and sisters instead. There is nothing wrong or disturbing about having your period; it is a normal part of life for girls and women.
Your periods for the first few years might be irregular, starting and stopping, and might be different when you’re sick or feeling stressed. After this time, your periods will be normal. The menstrual cycle runs from one period to the next, often between 21 and 35 days. Your period can last one to seven days. It is recommended to track it on a calendar so you know when your next period may start. Online apps can also help.
