Doctor's not concerned, but I am?

Br

My blood pressure has been spiking in the morning for the last few days. Causing things like nose bleeds, my palms and bottoms of my feet to sweat, mild headaches. I went to L&D yesterday and they held me for two hours, until my blood pressure stabilized. My labs came back fine. They gave me some fluids and sent me home. I'm experiencing this again at the moment. I ate a cheese stick and some almonds, and I've got a glass of ice water. I don't know what else to do. I work and obviously cannot put up with this while I'm working. Any advice? 38w1d.
