With most traditional films, complete fix happens in 2 minutes time if using a Rapid Fixer. Double that and some with traditional fixer. Tmax will take double that. Either way, it's pretty quick.
Since OP is using 35mm format, unrolling the film to inspect is basically really not an option, not to mention seeing if there are problems with wet film isn't easy either unless the problem is severe.
It's far easier and practical to switch to rapid fixer if not already and do the complete processing.
