160/100ish or over I would contact them as that is stage 2 mild. Your 4pm sitting is concerning. I would definitely call if the next one isnt better. Sounds like your plug might be going walk abouts too.

Got my fingers crossed for you - if nothing else for another week. Good thing you have the monitor there, but I would check it again to make sure it hasnt gone up from the last. If it has, call it in.
