I took my last Depo shot June of 2011. I was due for another shot in September. I did not get the shot because I was informed that you should not be on the shot longer than 2 years because of bone density issues. Well, I have been using the bathroom frequently, and having signs of pregnancy that I had with my other 4 children. I took a pregnancy test and it came back negative but I have also felt movements and fluttering. It's not gas, because I will feel the fluttering or movement and nothing else. I need some help? to this day, i have not received my period. someone please help!!!
