It seems likely that what you experienced (bleeding after intercourse) is not necessarily a reason for panic. Since you have a medical history of a removed uterus, it is possible that you might have experienced the bleeding due to mechanical trauma during the intercourse that caused a minor wound. The wound may well heal itself within a short period. Another possible problem is a bacterial vaginosis that, combined with the friction from the intercourse, may have caused a disruption of the vaginal mucosa. If this condition appears again, you might want to visit your gynecologist for a physical examination and vaginal swab.
