Good that she's at a safe number. I'd get a +6 to see if she's still dropping.
If the +2 is about the same as the PS, it's usually a pretty normal cycle...gradually down to the nadir and then gradually back up by the PMPS
If the +2 is higher than the PS, it usually means there's a bounce going on and you can usually not worry so much about testing.
If the +2 is lower than the PS, that's your "early warning" that she might be going a lot lower later in the cycle, so it's important to keep a closer eye on them.
