I came off depo in March 2015 (well didn't go for the injection that month). My periods returned to normal after a couple of months. However 5 months ago my period came 4 days early, the next one came 5 days early. Then I had a normal period at the normal time. The last two months it has been on time but only lasted a day or two and been very light. Anyone have any idea what might be going on? I'm starting to worry something is wrong with me... Could it still be affects of depo 15 months later?
