I Just Learned That My Hemoglobin Count Is Too Low

I just learned that my hemoglobin count is too low at 9.1. All other results were within normal range. I am a 75 year old woman with controlled diabetes, hypertension, and elevated cholesterol. More blood was taken today and I am awaiting results of a stool sample submitted earlier this week; however, I am also a raging hypochondriac and my internet search is raising all kinds of anxiety. Is this level of 9.1 serious?
