Some period questions?

The first year you get your period, it is usually pretty irregular. How much you weigh is also a factor. If you are very thin, you may only get 4 periods a year. Your flow is pretty heavy, but it is still regular. Nothing to worry about. Common signs of starting your period occur a few days before. Sometimes your breasts will become very sensitive, and your lower stomach may be upset or start cramping. If you're a serious ballerina, then you'll eventually have to wear tampons. If it hurts to sit down, you didn't put it in correctly. You shouldn't even feel it if you wear it. Depending on how big you are and the heaviness of your flow, you could probably wear any size tampon. If you still have difficulty, start out with a junior tampon, and work up to regular. Any brand will work pretty well, but don't get the cardboard tampons. Hope this helped!
