I have had straw colored more frequent than usual stools for the past two and a half to three weeks, my gums are bleeding, the last two days that I woke up I felt nauseated, today I have been nauseated all day long and have vomited several times, I feel very light headed, and stepping on the scale I noted a six pound weight loss in the past two weeks without trying. I am a female that is 38 years old, should I be worried?
