Hi there Lanena. If all your hormonal tests are within normal limits & your gynecologist has reassured you, you have nothing to worry about. However, you may want to ascertain if you have any bleeding/clotting disorders eg hemophilia etc in your family. You may want to do some blood tests to evaluate the bleeding & coagulation cascades eg Bleeding time, clotting time, PTT (partial thromboplastin time ) etc. & if all these turn out normal (as i feel they will be), then consider using a local lubricant before sex as friction /trauma may be causing the bleeds. I take it there is no foreign body eg loop etc involved else this can be contributory. Hope this was useful & good luck..Dr Praveen Rodrigues MD Dermatologist & venereologist, Bangalore, India
