Okay so I am like completely uneducated when it comes to blood pressure. with my daughter the highest it got was 176/98. so I know that's high. at my last appointments it was 133/76 so is that normal? borderline high? I'm not sure and they don't explain it. like with my daughter they didn't tell me it wad high my ENTIRE pregnancy. my doctor caught it at 37 weeks and I had my daughter that night due to preeclampsia. so I'm trying to keep an eye on it this go around and was wondering if that's okay?
