Hi, dear I have gone through your question. I can understand your concern. You have postcoital bleeding. You should go for Pap smear test which you have already gone through. So wait for the result of that cervical cytology report. Don t worry most of the time its not serious condition. Your contraceptive injection doesn t cause post coital bleeding. Moreover also check your husband s semen for blood. If blood is present in semen then you may feel that its come from your cervix. Blood in semen is due to injury or trauma to urogenital tract, tuberculosis or malignancy. But most of the time it is self limited. If it remains persistent then further examination needed. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
