blood pressure is creepin'

I went in for my NST today, and passed. Blood pressure was high. We rechecked an hour later and it was still high. They sent me home, and told me to watch at home. I did, and it's been high. I called my OB to let him know and I just got a call back. He wants me to go in for monitoring.I negotiated to take another pill now and see if it improves. If it does, great. If not, I'll go in to L&D triage and have them monitor me and run labs. It's tough, because I'm checking w/ a different cuff than what they use, so it's hard to tell how high it really is. Only way to verify that is by going back there.
