I am currently on the depo provera shot and have been for about 5 months now. I had pneumonia about a month and a half ago and they put me on some strong antibiotics. My doctor told me that my birth control would be ineffective while on the medicine. Well, of course I didn't listen and had unprotected sex. I've been bloated, had migraines, and I got sick last night while I was walking around Walmart. Earlier that day I didn't have much of an appetite. I've been extremely grouchy and having back pain. Sleeping a lot too!! I've taken 6 at home pregnancy tests and they've all come back negative. I took them about a week ago. A couple hours ago I had to pee and a tiny little black blood clot come off on my toilet paper. I have been spotting with some discharge. The spotting has been a copper color. Not fresh blood at all. Before I seen the blood clot I was cramping very badly. Can someone give me answers, please?!
