I have irregular periods all the time. my period is due next week however i am having red tinted discharge for the past four days. what's happening?

Menses: When you are young it is often the case that your periods are irregular because of an immature pituitary ovarian axis. In simple english, your brain and ovaries don't talk well to each other. Sometimes, there are structural problems such as polyps and fibroids that occur but those are usually when you are a bit older. See your gyn and get an ultrasound. Get a pregnancy test also.
