Before my son was born 31 years ago, before Libre and before CGMs etc, I had an endless series of massive hypos. On about five occasions I was carted off to A&E in an ambulance. The snag was that they would put me on a glucose drip, but then insisted I ate brown toast befors I was discharged. On every occasion this caused a spike to 22 or 23 mml within an hour and a half. I was finally prescribed glucagon which my husband had to inject, if he couldn't wake me up in the middle of the night. He could tell I was hypo because of the waves of hot, damp air from me which fortunately disturbed his sleep. My son is fine, with no medical problems, no medical history to take into account. He has a 2:1 degree in Maths and only worries about his student debt. You were lucky your team were re-assuring. The fact is, every female type 1, every pregnancy and every baby is different. I was worried senseless by some rubbish I was told by a GP, who knew nothing about me or my baby. Keep calm and ask your team for help. More blood tests are probably a good idea, if the technology isn't proving reliable, Good luck. You can do this.
