They'll most likely put you on bed rest, I had very high blood pressure (avg about 165/95) with my first, so high that if I didn't have a sonogram before my Dr appt she would send me to hospital for a NST (non-stress test) afterwards. I didn't have any symptoms though, no blurred vision, headache, swelling nothing at all. Just take things easy and don't over work your self, and just listen to your body, it will be ok!
