Many parents feel awkward talking about periods, especially with pre-teen girls, who can seem to get easily embarrassed. You can remove the tampon at any time using this string. A period happens because of changes in hormones in the body. Periods usually happen about once a month. This is really up to you. And others only get a period about once every 6 weeks.
Your periods will start when your body is ready.

Keep a spare pair of pants and tights at school or in your bag, and avoid wearing light-coloured trousers and skirts during a period, just in case. For the first few years after a girls starts her period, it may not come regularly. It explains what to expect and how to cope with periods. Most girls need to change their pad, tampon, or menstrual cup about 3—6 times a day. Further reading for girls "Periods — what you need to know" is an FPA leaflet that uses cartoons and speech bubbles to explain periods and how to use tampons and towels.
