Gestational diabetes if you low blood pressure and low blood sugar

Hello mummies, Have been reading up here and there and seen posts of being careful of GD as well as looking out for sugar intake. Wanted to know if I have LBP and LBS, could I have GD? I do drink a can or packet of pokka Green tea usually everyday. But ever since I found out I was pregnant I actually stopped drinking because I was a little scared. #advicepls
