Hello, well from the history you have given, you may be in a phase of attaining menopause
, as you are 49 years.....yes white discharge with amine like odour is due to bacterial vaginosis
.....i would suggest you to consult your gynaecologist...Bacterial vaginosis can be treated with antibiotics like metronidazole
should also be ruled out, as you have frequent urination
......A detail history and examination is required before coming to a conclusion. ......Also you need to keep your perineum
clean and hygienic. ..you need to void and clean your perineum following intercourse. ...hope i was helpful to you. ...
