Yesterday went for wk 34 checkup & my blood pressure was 148/80, which they said was borderline high. So, they laid me on my left side for 2 min & it immediately went down to 130/70. They said it was fine & happens often in the 3rd trimester. They said just to keep an eye out for common high blood pressure symptoms, but I'm afraid I won't catch the symptoms & it'll keep increasing... Anyone have this happen at a checkup?
