Low blood sugars?

Hi! I was diagnosed with insulin resistance last year, and started trialing a cgm after meeting with my doctor last week. I’m not having high blood sugars, nothing over about 110 over the 5 days I’ve had it, but I am having low blood sugar’s about 3-4 hours after meals (between 68-58). Is this common? The way my doctor explained it I wasn’t expecting my sugars to be so low. Interested in hearing other people’s experiences.
