My BP just creeped up in the previous two pregnancies a few weeks into the second trimester- one pre-e was diagnosed around 30 weeks (but didn’t progress quickly, so was induced at 37W), the other had elevated bp and started to get protein in my urine just before 37w, but at 37+1 bp got realllllly bad and baby was delivered that night. Didn’t have any of the “usual” symptoms- best way to describe it is I started to feel gross... not the miserable uncomfortable late pregnancy feeling but really bleh haha. Not super descriptive - I know! (And I recognized that feeling the second time when my Blood test numbers started hinting at pre-e developing). No swelling/vision issues/headaches/upper right quadrant pain they say to look out for- go figure! Thankfully BP is currently normal!
I took baby aspirin last time (under Ob guidance), and that may have held it off later? I’m on it again this time, along with vit d and magnesium supplements (again, ob recommended). It’s all an “it may help” thing.... I think stress/anxiety contributed to elevated bp in some ways, and that took a toll on my body too. Chasing two kids around and working, I don’t have as much time to sit and worry!
