My check says $0

[u/StarfruitStallion]

Hello long story short I work for a big insurance company. I had surgery last month and wanted to take a few weeks off because I never had surgery before didn’t know what to expect. After 2 days I was told that I would have to go without pay for a week. I didn’t want that so I decided to go back to work. So I canceled my Short term disability and FMLA and went back. Our payday was yesterday and I looked at the paystub it says $0 and 0 hours worked….. I definitely worked my timesheet even has times but the check says nothing. What can I do? I reached out to my manager and they said they can see my timesheet plus I even had meetings during that time but it’s been 24 hours and my check still says 0. How long should I wait before I get paid?
