Blood sugar low

Ana
Hi moms, I am 7 weeks and 2 days pregnant, I have already seen my lil embryo with heart beat. Just lately I have been very nauseas, shakey, light headed, dizzy. My husband has diabetes so I checked mine and he said my sugar is really low... does anybody else have this happen to them, should I tell my obgyn, is it normal that my sugar level gets low?
