At what point would you go to the hospital

I had preeclampsia and hellp syndrome with my last pregnancy and have been monitored very close this pregnancy. Everything has been fine so far. I’ll be 35 weeks tomorrow. Today I feel off. Dizzy and light headed a little bit of blurry vision. My blood pressure is high. I’ve taken every 30 mins and it was 137/100. 137/102. 151/100. Last 3 readings. I’m supposed to go in tomorrow for nst and blood work. Would u go in today or wait till tomorrow and just keep checking? I don’t wanna make a pointless trip to the hospital. Already have had a couple visits this pregnancy and felt stupid for going in.
