High blood pressure ???


At what time would you go to the emergency room for blood pressure ? Ive been the last two days at aroubd 140/95. Idk like at what point would be emergency room blood pressure. My ob is aware, they did blood work today for preeclampsia, and i have to monitor my pressure twice a day at home. Im 29 weeks pregnant, so im just tryna figure out like at what point would be the point i shud just go to the ER. Ive been feeling wierd not like headache, but just outta it like foggy and sooooo tired. But that cud be normal so idkk. Any adviceee?
