I;m thinking the same thing as PP, 5.1 is low, anything under 5 is considered 'hypo' for me. my specialists want my levels to be at 5.5 after meals, anything under 5 and im eating sugar like a mad thing because these pregnancy hypos are awfull!
if it makes u feel better my levels when i was diagnosed were 26.8 . i really wouldnt stress too much hun, if they think u DO have it it looks like a very minor case and u shouldnt need any insulin
Thinking of u
