For the past 2-3 weeks I have been having these symptoms. Around Christmas it started and I thought I picked up stomach bug but it has persisted. At times I become extremely nauseous and my hands get very cold. I feel like maybe I could pass out...then I had some cramping with brownish discharge for several days. I'm on birth control and thought maybe I was pregnant so I stopped taking them. At this point the cramping has stopped but the nausea still occurs with off and on constipation. I'm planning on seeing a doc but am baffled. Several pregnancy tests have come back negative. Any thoughts?
