I'd recommend waiting. My wife had the same problem at the time of her physical. The tests will show blood in the urine, so it could appear to be a serious problem (the concern being that it might mask a problem if explained away as menstruation.
Understand, too, that each round with an MA is at least 3 weeks, so at a minimum is longer than rescheduling your physical would require.
As Suniel said, the process is long enough as is. Don't increase the risk of getting into the MA black hole. I would reschedule.
