I'm 42 years young. After I turned 42 there were months I did not see my period at all, for 2 to 3 months at a time. It went from not seeing them to now I see them regulary.

I started my period on the 1st of this month, that went find. Now it is thr 21 and I've been spotting what appears to be brown blood for the past 4 -5 days. What could this be?
