Blood Pressure Question!

Hey everyone I was just wondering out of curiosity does anyone else blood pressure ping pong all over the place? I'm 28 weeks today (yay) in the hospital on bed rest for a rare TRAP pregnancy just for monitoring and contractions they've had to stop twice and so there just a lot of stuff that even my doctors don't know what's "normal" considering how rare TRAP is. I've always had low blood pressure so I'm curious. I've been all over the map with my blood pressure and everytime they take it I'm one extreme or the other. Last night I was 147/72 and this morning I was 102/51 and I would say my usual is probably 110/60 ish. I'll have a check of high, one or two of low, and then back to high. I've been having headaches but they have been able to be controlled with tylonal until this morning and my vision is a little fuzzy now as well but I had a lowish reading so I'm guessing that means I'm not preeclamptic? I'm allowed to walk around my floor and I think if I get diagnosed with preeclampsia then they take my walking around privilege away. I'll be here a total of 53 days before she's born at 34 weeks so I'd like to at least walk around some. I've never really dealt with my blood pressure a lot other than it being slightly lower than the average until now. Curious to see what everyone's experiences were! Thanks in advance!
