High BP after birth

I had high BP during my pregnancy which lead to my baby being born 3 weeks early. After giving birth they were super on top of taking my BP during the 4 days I was in the hospital and my BP was PERFECT. However since being home it’s gone back up a lot and so I called the doc and they can’t get me in til Friday. I did some googling to see why the BP going back up could be problematic and saw that if could be postpartum preeclampsia which could cause stroke or seizure and now I’m super scared. Anyone else have this happen to them? Do they hospitalize you again or just put you on meds? Wondering if I should call the doc and try to get an earlier appointment or if it would be okay to wait til Friday when I was originally scheduled.
