Okay...I'm 19 years old and i have always had a regular period. 2 week after my period i had brown discharge for about a day then i experienced cramping in both sides of my stomach then on the right side around my back. I had some milky looking discharge but it didn't really smell. A few days before i was due on my period i noticed spotting in my nickers. A day after i came on me period which was normal although they are usually really heavy. 3 days after my period was very light so i thought i was coming off then still 5 days on i kept having spotting. I have no pregnancey signs although i do go to the toilet alot, It dosn't burn or itch or anything. I got abit of slight cramping yesturday but didnt last very long and wasnt really painfull. I am feeling more tired than usual but not overly tired. I cant get into my doctors for another 2 week so just wanted an opinion to keep my mind at ease while i wait. What could this be?
