high blood pressure

Have any of you second time moms or moms who have already delivered suddenly developed high blood pressure at 39 weeks? They checked me Wednesday and it was high, but I was seeing a different dr due to mine being on vacation this week. So, they monitored baby and set up an appointment for this Friday to recheck.  So, today I went back and they checked three times--all high. Since I have been having mild headaches, and I had gained two pounds in between those two days, I'm going in tomorrow for a NST and possible induction based on the results. I had perfect BP, except once when I had been sick, all throughout. I'm nervous. I wanted (and had hoped) baby would come early, especially since I have been dilated to 3cm and have had contractions off and on for a while, but induction scares me a little.
