Will I need to redo my physical or inspect if my last MEPS physical was within 30 days?

Passed my MEPS physical about two weeks ago. I am prior service, and had to wait for my waiver to go through. Got word that they were approved. Now that it has I will be going to MEPS again for MOS selection. Will I need to redo my physical? My recruiter says I shouldn't even need to do an inspect since it hasn't even been 30 days, but didn't sound 100% on it. I'm not too worried either way, just trying to figure out how long I'll be there so I can decide whether to drive my own vehicle or not.
