Elevated bp

I had my 34 week checkup yesterday and my bp was elevated (148/86), so they had me lay down for a bit, then checked it again (150/76). With my last pregnancy, I was in the process of catching my urine for 24 hours due to borderline preeclampsia symptoms when my water broke. I was 38 weeks, so I’m a little anxious with it possibly happening a whole four weeks earlier😬 I go back tomorrow morning to get a recheck and then we will go from there. Is anyone else dealing with elevated bp in a subsequent pregnancy? How is your doctor treating it?
