I am a 27-year-old female. I have been on Depo-Provera for six years. I am not taking any other medications. Lately, I have been experiencing severe mood swings and have not been myself. One minute I am dancing around the room and could not be happier, the next I am either crying or very angry. Normally, I do not cry and I am usually pretty laid back. I have also been getting dizzy mostly when I stand up or walk up the stairs. I have trouble sleeping and or sleeping too much. I am hungry all the time, however, when I do eat I feel nausea. I have done some research and have found that these symptoms are both common with the injection and also with pregnancy. How do I tell, if these are pregnancy symptoms or if it is because of the Depo shot? I did miss my last shot three months ago. Last month I took a home pregnancy test it came back negative. Will a home test be enough to tell if I am pregnant or not?
