New to running- ankle pain!

Hi! I am on W2D2 of Couch to 5K and my ankles are KILLING me! I'm talking, could barely walk after doing my W2D1 workout last night killing me. They are doing better today (not 100%, but better), but I am nervous about my workout tomorrow. Did anyone else experience ankle pain when they started C25K or running in general? Is it because my ankles are weak from not exercising? Do I just need to work through it and strengthen my ankles as I go? I REALLY don't want to stop C25K because I am enjoying it so far. Something about finishing one of those workouts makes me feel super accomplished . However, I want to be realistic about my capabilities. Any advice would be appreciated!
