I have read that sometimes the vaginal wall can become so dry after menopause, it may be irritated and could cause some spotting or light bleeding. I would try some lubricant but definitely see a dr. as well. It could be a more serious problem. Best of luck!
i. am going through something similar. in the last three years, i have had 3-4 periods with the last one i would say has been over 2 years ago about a week ago when i went to the bathroom there was a little spot when i cleaned myself and it has done it everyday since. sometimes its a very small spot, and then the next time it is enough that it stains my panties. i have tried to research this on the internet but not really getting any answers. i didnt know if this was something normal or something i needed to check with my doctor. i hope you find some answers.
I would definitely make an appointment with a gyn to check this out, I could see it happening maybe a year after you have stopped bleeding, but four, I would get checked.
Hmmm, after four years of nothing, I think I would contact the dr for an appointment. Just to make sure everything is okay.
