Thanks for contacting with your health concern and after reviewing your history following is/are recommended guidelines: 1. bleeding after intercourse is very suggestive of malignancy [unless proved otherwise] since cancer of the cervix if detected early is completely curable. 2. Sex can make you bleed soon after your periods stop and some menstrual piece (debris) stay behind in the uterus and during sex due to contraction in the uterus wall the leftover can come out resulting in bleed, but if this continues to happen it is better to consult an OBGYN doctor. PS. Sometimes due to ongoing infection, the vaginal epithelium is prone to injury and sexual intercourse during this recovery period can cause bleeding especially after a forceful sex, so wait for few days remain abstinent from sex give time for epithelium to grow but if the problem still persists then see a doctor. 3. some other causes to exclude vaginal bleeding after intercourse are: . Inflamed cervix . Endometrial or cervical cancer . STD s/vaginitis/cervicitis . Uterine fibroid tumors/polyps on the cervix . PID (Pelvic Inflammatory Disease)
