<human>: I've just had my first period. Is there anything I should know?
<bot>: It's a good idea to keep track of your periods so you can plan ahead and make sure you have enough supplies on hand. Make sure you're comfortable with the basics, such as how to recognize your period, what type of sanitary products are best for you, and when it is appropriate to see a doctor. You may also want to consider talking to friends or family members who have already experienced their first period, as they might be able to offer helpful advice.
