Pay Period on Pay Stub is before my OPT Start Date

[Karthik reddy]

Hi All,

I Recevied an RFE For my H1B Application. 
USCIS Requested all my Pay stubs right from OPT to Present date(On OPT Extension right now) as part of RFE .My OPT Started on January 27th 2016,While checking my Pay Stubs i realized that my First Pay Stub has period of pay from January 1st to January 31st 2016.But actually my Pay started from January 27th only. As my company pay stubs have period of pay mentioned as  1st of every month to last date of every month  irrespective of Start date. Does it create a Problem.If so how do i expalin to USCIS

If that stub shows only 4 or 5 days of earnings, there is nothing to explain.
