Hi, Ive had some concerns about some health issues I have been having lately. For the past four or five months now, I have been experiencing, Headaches, Dizziness, Fatigue, Nausea, Late Periods, Lower than normal sex drive, disorientation, and numbness/tingling. Lately, everytime I have gone to the doctor they ask me if I am pregnant, they run a test and its negative. In the last month I have taken 15 pregnancy tests and they are all negative. Any ideas?
