how you know your about to start your period
Although a lot of girls get their first period between 11 and 13 years old, you could get yours anywhere between 9 and 16. How do you know itâs on its way? Watch for these signs. Puberty in itself is a big sign that your first periodâs on its way. Here are a few to look out for, too: 1  Developing breast buds: It can take three to four years for your breasts to then fully develop, but you can expect your period about two years after your breasts start developing. 2  Growing pubic hair: Just after your breasts start to form, you'll probably start growing pubic hair.
