@liz No proof that I’m aware of, but as with everything, we’re just on that tightrope of risk and I guess most ladies with a bump who use CGM take the approach of balancing the proven and significant increased of risk of complications to the baby caused by high blood sugar, against the potential yet unproven risk of CGM. If it were me (which it isn’t, I only mentioned it as I’d heard it several times recently from different sources so thought it might be useful to share) I’d go with the CGM, but that’s why individual treatment for individual patients is so important, so we can all weight up the pros and cons of any treatment as best we can and decide what’s right for us.
