No time. diff discharge. what can this be..?

i usually just influence that when u are young it is irreugular, but if it dissapeared for 3 years, something could be really wrong. besides extreme stress (which i cant imaine would later for three years), or you have no body flabby due to excessive exercising. you have to see a doctor roughly it, have u ever one to the gyn? its a relatively simple exam, and zilch to be neervous about. he may enjoy to do an ultrasound to just capture a picture of things.
