High BP? advice please!!

Holly

I had preeclampsia three years ago with my second pregnancy with a csection at 36 weeks. This is my third and I'm 36 weeks pregnant with a scheduled csection in 30 days. I've had a headache the past 2 days and checked my bp.. 160/99. My bp has been low thus far (120/70 and lower). I feel it is high though. should I just relax or go into labor and delivery to get checked! idk.. I hate sitting there and wasting a bed if it is truly nothing!
