spotting aproximate 16 months after last period

hi everyone. i had my last period around 16 months ago. i am 53 years old.
today i have a bit of cramping and a bit of brownish discharge when i wipe. .not much.
i wondered if other ladies have had this happen …is it quite common?
someone said if you have not had a period for 12 months then you wont get any more . do some women still have a period or bit of one after not having one for the last[ aproximate ] 16 months?
hopefully some body can let me know has it happened to them. thankyou.

where you check for fibroids

Hey, pretty much same thing I am going through. It has been almost 12months since last period and I started spotting. Then it was a brownish spotting a month later. I did have a pap 2 months before and everything was fine. Did you find out anything?
