Welcome to the Fitbit Community, @Roianne.
I am sorry to hear your Charge 3 tracker won't sync. I am here to help. I recommend following our troubleshooting instructions from this help article: Why won't my Fitbit device sync?
Keep me posted on the outcome. I'll be around if you have any additional questions.
