I'm not sure I have an answer either, but I had protein at +1 last week (at 24 weeks) also and my mw wasn't too concerned. (my bp is also typically very low, and a bp of 120/80 for me, at least would be high)
From what I understood from my mw, it's not as much as one reading that is of concern but changes over time, which I guess she's having you monitor your bp more closely,
