First Period At School Dear BeingGirl Experts, What will happen if I'm at school with a friend just talking and all of a sudden my period is here? Sophia --- Dear Sophia, Your period will probably not come flowing out heavily immediately from the start. More than likely you will notice some dampness or wetness and excuse yourself to the restroom to find that it has begun. You should be carrying your menstrual protection in a backpack or purse in case you do start. If you think you are close to getting your period, you can begin to use Always ( www.beinggirl.com/product/always) pantiliners to make yourself feel more comfortable should you start your period. Check out the location in your school where emergency menstrual products are kept so you will know who to contact in case you are caught without supplies. Sometimes it is with the school nurse, the health/physical education teacher or even the school secretary. Good luck, Your BeingGirl Experts Learn about having your first period at school. get expert tips and advice from BeingGirl.com.
