Scared need advice

A little long but please give me some advice on what to do next. So i just had my last baby 5th to be exact 1/17/24 and i had pp preeclampsia but went away after 6 weeks now my bp has sky rocketed over the last few weeks out of the blue. I have no infection bc my white blood cells aren't high. I was a little dehydrated but overall they said my bp would be low and ive felt like this for 3 weeks now and i went to the hospital and i wasnt dehydrated the week prior and still had same issues but never knew it was my bp bc i didnt think this would be happening to me again until i started monitoring it again but ive been over the last few weeks due to tingling in hands and feet, dizziness and sweats and i keep getting sent home bc theyll check after laying in a hospital bed for 3 hrs. I have a dr appt tomorrow at 2 but scared i wont get the help i need and i dont feel okay but dont wanna waste my time as they said dont come back unless my bp is 200s/120s.. I just need peace of mind. I want to live for my kids. Now im paying health wise.
