I've been coming off Depo for about 2 months now. I was due for another shot in Feb-March but I didn't want it. I bleed everyday. I have been ever since I started Depo. About 4 1/2 weeks ago I had unprotected sex. I was scared so I took the Plan B pill 24 hours later. Now I am having trouble eating. Every time I eat, I feel extremely nauseous and I'll want to throw up my food because it hurts my stomach. I feel full almost all the time. I don't know if I missed a period or when I should come on because I'm ALWAYS bleeding. There isn't one day that goes by where I do not see at least a small amount of blood. My emotions are out of whack and I feel so tired. I took two pregnancy tests and they were negative. Could I be pregnant?? What are the chances?
