I was on the depo provera shot for 3.5 years, I discontiued the shot in July of 2009. I had my first normal period May 7 2010 and I haven't had one since, what could be wrong? I took a pregnancy test but it came up negative.

The depo can take up to a year to get a normal period times some month you might have one the other may not I got off depo and went three months without one if anything call the docters office and get a blood pregnancy test but it is normal to miss one after the depo
