Low estrogen often causes high blood pressure.... So the mind boggles why you were told to stop it.
I am really fit (so says my Apple Watch

) and work out 4-5x a week, do 10,000 steps a day blah etc.... And I'm slim. I've NEVER EVER had blood pressure problems in my life.
Suddenly, with all this peri-menopause crap, I began to get very high blood pressure spikes. Not consistently, but randomly. One night I laid awake ALL NIGHT (with my low estrogen symptoms - including palpitations, inner tremors, heart beating hard and fast) and then went to A&E the next morning as I was worried I was having a heart attack...
ECGs were always normal. But my blood pressure at the hospital was 183/90 which was ridiculous. Like you I was told to monitor it for a week. It was normal every time I happened to take it, because I wasn't testing during one of these spikes.
I am now on high dose HRT and my estradiol is around 850pmol with a generous amount of progesterone and regular testosterone doses. My blood pressure is completely normal again.....
