I haven't had anything to drink (two beers) since may 1st. I took a etg-500 urine test on the 7th. Will I pass

Probably.

Most likely but that test has been know to give false positives

I only had two beers that day

The EtG should be out of your system after 6 days and two beers. Incidental exposure to products containing alcohol or false positives are possible, but based solely upon your alcohol consumption and the time that has passed, you should be clear.
