I lost my virginity on September 27, 2013. I enjoyed it. My period started September 28, 2013. Now it is October 6, 2013 and my period is still on. My period is usually days long. What could be the problem?

There is no problem. That time span is normal but don't just take my word for it, also ask your doctor.

OK, I asked her. She said it's normal since my periods are irregular sometimes.

But it continued until October 11, 2013. Then disappeared for 2 days and I am bleeding again. So I emailed my doctor again.
