Better time in range worse A1C

Hey everyone. I don’t really need suggestions but I’m pretty pissed. Just had my regular check up and my A1C went up from 6.2 to 6.5 but my TIR under 180 is 90+% and under 140 is 70%.

I’m just so frustrated. I’ve been going to the gym and eating better and the damn numbers are sliding the wrong way.
