I don't know if its my period or not. Help please!

I have mucus discharge even when I am not on my period. Is this normal?

A variety of different fluids flow during a normal cycle... different colors and consistencies, etc. You can learn a lot more about it here:

The thing is, you need to pay close attention and make notes on a calendar to help you learn what's normal for YOU so you can contact your doctor when something abnormal your body occurs.
