Gradually bleeding more after having sex for the first time. Also feel sick.

Patient: I had sex for the first time about 10 hours ago. I am starting to bleed more then when my hymen first broke and I have a headache, nausia, and vomiting. My vagina throbs and my insides get a sharp stabbing pain whenever I move from one side to the other (or sitting to standing and visa versa) and I am really scared. Should I see a doctor or is this normal?
