One month period after discontinuing depo shot

Patient: My last depo shot ended i January 2013 and i decided not take the next one at the beginning of Feb. 2013. I am 43 yrs old by the way. Immediately my period returned Feb 8, 2013 and i’ve had it since for 1 month. It’s not heavy but light. How much longer will this go on. I’m tired of having my period? ugh

Doctor:
