Can anyone help me cure my health anxiety whilst pregnant?

So most of you unfortunately know of my anxiety emails.
I’m loving being pregnant honestly I am, but I’m a hypochondriac and now my fear is falling on high blood pressure… I’m 29 weeks, my blood pressure for the entire pregnancy has been averaging 120/65 and now it’s rising to about 120/72… is this normal?
My BP before falling pregnant was always around 120/80.
I have a monitor at home and I’ve been taking it insistently and it changes from 130/77 to 110/73 to 109/67 – is this me freaking out… I take it 4 times within 10 minutes…. Can your stress about something cause you to have higher blood pressure?
At the doctors yesterday it was 120/70 but she took it again with me laying down and it was 120/60.

so what am I doing to myself or might I have to monitor my blood pressure now?

Sorry – I know I’m freaking myself out and it’s driving me nuts – but I need to be aware as well.
Thanks so much.
