No. Your medical is still valid. You do not at this point have to renew the medical if it was filed with your application. USCIS memo allowed them to remain valid.
From Murthy.com
We are pleased that the USCIS has once again recognized the unfairness and inefficiency in making all I-485 applicants retake medical examinations that expire due to USCIS backlogs. Accordingly, all I-693 forms that do not have Class A or Class B medical conditions certified will be valid through January 1, 2005, if the Form I-693 was filed concurrently with the I-485. This policy applies to all service centers and local offices.
This continuing policy has significantly reduced the number of Requests for Evidence (RFEs) that the USCIS otherwise would be required to send on I-485 cases. RFEs for new medical exams or supplemental information will still be required for cases in which the person did not have the required vaccinations at the time of filing the I-693, or in which there is still a medical concern. We appreciate the USCIS's continued approach to this issue and hope that the backlog reduction plan will soon work effectively so that the validity dates of the Form I-693 will not need to be extended year after year
