ovulation calculator question

brandonsbestgirl1

So my next period is not due until the 29th of july since my last one started on the 1st of july. I am on a 28 day cycle... when i put the expected date of my next period in The Bumps ovulation calculator it skips August all together. Does this mean i will not Ovulate in August? it just skips right to September. Im alittle confused here =/
