I am a 30 year old woman. I have had a lot of stress recently. I am almost a month late on my period but have taking 3 home pregnancy tests and a blood one and they were all negative. I have a 10 x9 focal nodular hyperplasia on my liver that was found over a year ago. This past weekend has been the worst. Friday night I was having right sided pain and very nauseaus and I even vomited once. On saturday my doctor had prescriped some bentyl for me and it seemed to help with the pain. I have had nausea everyday since then. Sunday and today the pain has not been as bad but for the past month or so I have had pain near my liver below the ribs on the right side. I know I am not pregnant so why am I so nausea.
