sex

On Tuesday night, my partner and I tried to have sex for the first time. He complained that I was not wet, but still he tried. I felt a lot of pain and stopped him. After that, I experienced no bleeding. But the next day, I saw a couple of drops of blood. From Thursday onwards, I was bleeding properly and had to go through one sanitary napkin a day. The bleeding has not subsided. I feel no pain in my stomach or back. I had visited a doctor; she said my hymen has broken and the bleeding is normal. She has also given me medicine to cure some infection. Six days have passed and I am still bleeding. My periods are yet to come (but delayed periods are the norm for me; it is usually six to seven days late). Does this situation seem normal or should I be concerned? I need your help and advice.
