Period Questions? *please help!*?

okay so your 13 and you got your period that is when your supposed to get your period . First you should contact a doctor or if you want you can tell your mom to take to a doctor but ask her for privacy and then ask your doctor if you can take birth control pills . But honestly since you are still young and just got your period i suggest u use tampons ( buy them from somewhere) to keep the normal pace for your period since trust me it is going to be irregular for a while until you reach a stable age like 16 or 18 maybe. Do not take the use the weight loss way because i did that once and i regret it because you will be losing your muscles and might turn anorexic just because you wanted to prevent your period . I hope you tell your mom though it is not embarrassing or anything its human nature.
