I have had constant diarrhea, bloating, cramps, fatigue, and tender breast for about a month now. I'm currently taking the depo shot as my birth control. I took a home pregnancy test a few days ago and it came out negative. My husband and I have unprotected sex all the time, could I be pregnant?

You have not said whether or not you have missed a period,therefore considering the home test read negative,I would say probably no, however I do think you have sufficient symptoms, which may be an infection of one sort or another,to make an appointment to see your doctor.

You could also ask him/her to do a pregnancy test whilst your there.
