Not sure if 120 is low enough that I should be wary of tonight? Don't have many test strips, more coming on the 15th.
I'd try to get at least a +4....if the +2 is lower than the PS, that's your early warning that you need to test again later.
How low is "not many"? Any way you can get to WalMart tomorrow to buy more off the shelf?
Don't have a car to get to walmart unfortunately.
