My girlfriend is having heavy abnormal bleeding during and after intercourse. this has been going on for the last 13 or 14 days not sure hats going on but need to know what to do asap..... shes not wanting to go to hospital

You : You are correct in being concerned. She definitely needs a medical evaluation. The problem is you can't make anyone go to a doctor or hospital. You can talk to her and explain to her that this bleeding is serious. She could be having a miscarriage, have an infection, cancer needs to be ruled out, as well as anemia due to all the blood loss, etc. Please continue to be supportive and encourage her to see a medical professional. All the best.

Hello. : Hello. I can't diagnose her condition. However this is worrisome. I am writing this answer 6 days after you wrote in with this. There is a concern that she may have developed a tear during intercourse. If her bleeding has not already stopped or she has not already been treated, then she needs to be evaluated by a physician. Prolonged heavy bleeding can lead to anemia and hypovolemia.
