Welcome to Health care magic
There are multiple causes for this type of bleeding. After menopause, vaginal and cervical mucosa becomes very thin, and sensitive,and your cough due to bronchitis
could be the reason for your bleeding.
Are you taking any Hormonal replacement therapy? Are you taking Aspirin?
Your age, overweight
, high blood pressure
and high Cholesterol
are all high risk factor for cancer of the womb also.So we must rule out cancer of uterus, and cervix.
I hope you go for your annual check up like Pelvic USG once in a year or two, Pap Smear, mammogram, and other annual check up due to your age, hypertension
Carol, I would suggest that you see the Doctor and rule out any of the above conditions.
