Hi Doctor, I'm nineteen years old and have had my period since the age of eleven. I've had a normal monthly period for years. In the past three months i've seen irregularites in my period. There would be 2 days of light brown vaginal discharge and then a day gap before i get my actual period that would last 8-9 days. This past month the same thing occured, but i didn't stop bleeding. I had the 2 days of discharge, then the 8 day period, but after that i kept getting brownish/red vaginal discharge for another 4 days. i started taking siberian ginseng and have noticed that instead of there being discharge, its just red blood. In total i've been bleeding for 18 days up til now. How can i deal with this and is it something to be very worried about?
