Pregnancy Info HOME

I've had some symptoms of pregnancy, like fatigue, nausea, increased urination, and I got ligh-headed a couple of times ...however...I have noticed that those symptoms are also the same as with diabetes. I was tested for diabets in November of 2003, and it came out that everything was ok and I did not have diabetes. I have taken a couple of home pregnancy tests and they say negative. I have had my period, but it has not been "normal"...I've had 3 periods and if I am pregnant I would be about 4 months along. My question is, how likely would it be that I was pregnant, and is there any symptom that I could have that would not be a symptom of diabetes? Thanks so much....
