Is it bad to use the CREDIT/NOCREDIT option in a pre-req course for Waterloo Optometry if I plan on retaking this spring?

Due to many extenuating circumstances I could not control in isolation, I got a 51 in Organic Chemistry 1 here at Uwaterloo. This tanks my average heavily, and we have the option to file a petition for a CR/NCR option which I am considering. It is a pre-req course, however I am retaking it in the Spring term to a) perform better and b) get the numerical grade they require for pre-reqs. Could this have a negative impact on applications to Waterloo Optometry?

The program is very competitive... I believe you'll receive a better answer if you ask admissions directly. :/
