Usually, no. For an active domain, renewal adds the selected term to the existing expiry date rather than starting a new term on the payment date. Renewing early does not, by itself, remove the time you have left.

Once the renewal has been processed, check the updated date in your domain management account. If it has not changed, ask for the renewal to be checked and provide your payment confirmation; payment and completion of the renewal do not necessarily happen at the same time.
