BP spikes

Has anyone had their blood pressure spike while being inactive. I’ve been on and off dizzy and fatigued all day. I haven’t done anything other than walk to the kitchen and back to the couch. I check my BP it’s never above the 140/90 but is close 139/88 with a fast HR. It will last maybe 10-15 min then go away.

I’m 33 weeks pregnant and had preeclampsia with my first pregnancy but not until 35 weeks.

I left a message for my doctor. Just hoping someone has some insight while I wait for a call back.
