I'm on ridaq 12.5mg and pharmapress 10mg for high bb is it safe to still take my estro-pause 2mg for hrt?

NO. 2 mg is too high. You should not use more then 1 mg. You have to use Progesterone also to balance the estrogen even if you have had a hyster. Progesterone, not the synthetics, stimulates the p53 gene to protect you from cnacer.
Yes. Because you have high blood pressure, you are at greater risk for blood clots. It might be better to change to a topical form of estrogen such as a patch or a compounded cream as this has a lower risk for blood clots. Of course dietary and lifestyle changes to normalize your BP and get off the medications would be ideal.
