My last period was in the beginning of December 5, for me a week early. I was caught on surprise. My periods are usually heavy and a week long with a complete stop in the middle for least 24hrs then starts back up. This month it was one day heavy then completely stopped for three days then spotting for a day then stopped again for couple more days with brown discharge started up for the thrid actual day after five-six days. The last few weeks I have been extremely hungry but losing weight. I cannot even wear my wedding ring. I last week or so been continues hungry or nauseous. Plus my sex drive this month has been extremely high. I took a pregnancy test late this morning but it came out negative. So, now I am not sure what is going on with me.Does anyone have any suggestions or answers?
