Discharge is normal and healthy. It's the vaginas way of cleaning itself and can change in amount or smell depending on where you are in your cycle. Sometimes it can be brown if you're spotting or near your period and some Birth Control can alter it too.
That being said, if it's ever cottage cheese texture, smells very bad, is green in colour, itchy, tender inside or not "normal" for you, then it may be an an infection and will need to be checked out.
