Its been a while that my girlfriend is bleeding in an abnormal manner. Her monthly cycle usually starts in the middle of the month but this time it was too early and had a visit to a doctor and said it is due to hormonal imbalance. It stopped after some bleeding and then again it came back with two days light bleeding. And then a tiny droplets of blood seen as of now. What could it be. Really worried. There is no pain or irritation. Help.
