I have been on the depo shot for almost 3 years. I missed my shot by about two weeks. When I got my shot I had sex about two weeks after. My boyfriend and I tried three times to get me pregnant in two days... This was this past Saturday and Monday. Yesterday, Friday, I had a bad stomach ache and I bled a bit. I haven't had a period in about a year now... Does that mean that I'm not pregnant? Was that the shot pushing out what ever was going to grow into a child... Or do I still have a chance of being pregnant???
