I am a Type 2 diabetic. My period is two weeks late, I have been having severe mood swings, having to eat every hour or get lightheaded or feel like I am about to faint, having irregular sleep patterns, and having bursts of energy at first but now just plain tired.  I have been getting VERY VERY nauseous. My sugars are irregular.  The only other time my sugar has been irregular is when I was pregnant 3 years ago but unfortunatley had a miscarriage.  Even when I am sick my sugars don't spike like that.  I began bleeding today.  Is is possible that I am pregant?
