high blood pressure

Sandi
Does anyone have high blood pressure? 
I'm always on the edge of high (high 130's/low 140's over high 80's). It spikes at the doctors office But totally normal during the 2 times I went to the hospital. My doctor has only said they need to watch me closely (weekly appointments) and mentioned that I might need to deliver early. Nothing about what to do to lower it or possibly leaving work early or bedrest! 
Anyone else's doctor give them more info? I'm freaking out that at anytime I could spike alittle at the office and they'd force an emergency c-section :(
