I was on the depo shot for 2years, I didn't have my period at all while on the shot, I got off of it April 6, 2011 because my boyfriend & I were talking about having a baby. I have a 28day cycle, last month my period was late but finally started on October 21st. This month I am so far 3 days late on my period. I usually feel cramps about 2days before I start, well I only felt them for about an hour, cramping stopped and haven't felt cramps since. I am NEVER late always EARLY. I haven't took a pregnancy test since last month a day before I started. Whats the chances that I am pregnant?
