I had my tubes tied after the delivery of my third child by c-section in June of 2003. I never have had a regular menstrual cycle but I am 37 years old and the last two years I have been having a period every two weeks, with alot of large blood clots . My breasts have a discharge that is a dark green color and my bra smells like soured milk. I had a mammogram done because of the discharge and the results came back normal. I have been having feelings like something is moving around in my pelvic area on the right side and I have been experiencing dizziness, feeling like I was going to faint with sweating and nausea at times. I feel very tired , weak, and sleepy . I'm just getting through with my period, the last few days I have a brown discharge, it's been shorter than normal. I normally go for at least 12-14 days. This one only lasted about 10 days with a flow that is not normal for me. What could be wrong with me? What would it feel like if my tubes are coming untied and would or could I feel it untie? Could I be pregnant?
