-i had my last period at a normal time
-i am on the pill, and i took it as directed (yazmin)
-my period this time was about normal (maybe a day later at the most)
-it started with browish discharge (which i have experienced before)
-i used a tampon for the very first time which contents seemed normal, like the regular red blood, when i took them out (i used 2, then it stopped)
-and it started again a couple hours later with the darkk brown discharge and some normal bleeding every now and then...
-it has lasted for about a total of 4 days.. and i usually have very short periods anyways.. so this seems normal.

what is this? :S

and by the way.. im only 16.
