Hello, I have gone through your query and understood the concern. After menopause, there is an atrophy of the mucosal layers and this can lead to spotting due to trauma after any vaginal procedure or intercourse. This is the most likely reason for your symptom. Yet, in view of your age, please see a specialist for a proper examination. A pap smear should be taken as part of routine checkup. Lack of lubrication leading to trauma during intercourse can be checked by using either hormone implants or K-Y jelly. Infections, if any, should be promptly treated. Hope you find this information useful. Take care.
