-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 anyway.. so this seems normal.

What is this? :S

And by the way.. I'm only 16.

My situation is really similar, Im 17, my period came on the day it was due but as it was ending I spotted.
The condom broke 2 days before my period was due and when I got my period I thought I was safe, but I feel like I am experiencing some symptoms...
Is it possible to be pregnant?
