Your first period will really hurt and there's nothing you can do about it.

Many women hardly notice any discomfort at all during a period. Others might have what are called 'period cramps'. These are usually aches or cramps in the lower part of your tummy. Or sometimes you might have an ache in your back or along your inner thighs.

PMS (Pre-Menstrual Syndrome) is all in your head.

Before your periods, hormone levels in your body skyrocket meaning you may feel irritable or unhappy. Pre Menstrual Syndrome (PMS) is a physical condition and can't simply be dismissed as silly or imaginary.

You can't get pregnant during your period.

Well, it's unlikely but it's not impossible - particularly in the middle of the menstrual cycle. Don't risk it and remember that unprotected sex also exposes you to a host of sexually transmitted infections. Take care at all times.

You shouldn't wash your hair or body during your period.

Some girls sweat more during their periods and there's no reason not to stay clean and fresh.

You should always rest during your periods.

Listen to your body and do whatever makes you feel good. Your period is no excuse for lazing around; in fact a little gentle exercise and stretching is really effective in relieving period pain.

People can tell when you're having your period.

Again, totally untrue. A quarter of all women between the ages of 10 and 50 are having their periods at any one time and it's impossible to tell who is having one and who isn't.
