I didn't finger prick as the graph showed i'd been out of it for almost an hour! Kept an eye on it and it just kept going up and up. Finger prick halfway through that showed i was a bit higher than the sensor showed! I think i missed it because i'm really tired, struggling to get myself up and going atm, and my younger daughter rang last night and as shes been working away i haven't seen her in a few weeks so felt a bit emotional.Its around 48mmol, did finger prick confirm as you say its not like you to miss one xx
