Creatine can raise creatinine but has never been shown to lower GFR in healthy people and long term studies don't find negative impact kidney function, You could stop and retest GFR sure. Do you have a pre existing kidney issues that has you testing GFR regularly?

I never test a CMP without fasting and having taken at least 72hrs off from the gym and creatine. You can easily inflate Creatinine test not doing all of those things.

A creatinine test also will not account for your added muscle mass, or a high protein diet.
The number you have is most likely eGFR (estimated GFR) that is a formula that uses creatine, albumin, sex, age etc to estimate your GFR. Creatine use can increase creatinine and consequently eGFR. So can lifting weights and having higher than normal muscle mass.
If thats the case you can a test called cystatin C test that is not correlated to muscle mass. Or also have a 24 hour urine creatinine clearance.
Again eGFR for weight lifters a lot of times will underestimate your kidney function
