How do you know when you are going to start your period for the first time?

Actually you start by getting moody and irritable. Like you would cry over little things you normally don't. And then you would start getting headaches for no reason but an easy was to treat that is just a cold washcloth. Then you will find white or clear smelly discharge in you underwear determining the period is soon. And soon you could or will develop burning and that is a warning sign that you are about to have your period. But don't worry it doesn't hurt! And even if it did it would only hurt a little! And this is said by specialist Lianne Roberts. Believe me.
