Low blood sugar

Hi ladies- am currently 3 weeks 6 days pregnant. For the last 4 days I've been having really bad episodes of hypoglycaemia after not eating - I have some sugar and juice and I inmeadiately feel better. I don't have any history of diabetes whatsoever but now I'm freaking out as I read that it's super incommon to go hypoglycaemic during pregnancy without having diabetes?? Anyone else experienced anything like this in early pregnancy without being diabetic?? Thank you!
