Ive been on Depovra for about 2 years now. But this last shot, something was different. I felt this pain right away. It is a sharp pain and it is usually only on one side but it switches from side to side and it shots all the way through my anus. I also at the time thought I was pregnant, but I took a test and it came out negative. I'm worried that I could possibly have an ectopic pregnancy or be pregnant in general. Or have something really wrong with me. Please help!!
