I am a 34 year old female. I was on the depo shot for about 2 years before coming off it about 1yr ago. My periods have been irregular but within the last few months it seemed like I had some sort of consistency. I got my period the first week of Dec. that lasted about five days. About a week later I got it again, but it was more like brown spotting that lasted about 3 days. Today is now January 30 and I have not gotten my period since then. I have taken some home preg. tests and they have all been negative. I am having some white discharge, cramping (like my period wants to start, this has been going on for about 5 days), loose greenish black stools and headaches. I do not have any breast tenderness or nausea. Could I be pregnant? I do have an order from my gyno for a blood test, but need to get time from work to take the blood test. Could be a week before I can get it done. Any advise would be greatly appreciated.
