Yeah I would esp with the elevated BP readings and the headaches. They may want to monitor you because of that. Please call your OB.
YES! You must see a doctor. This value is in the hypertensive range which could be dangerous for you and baby. Preeclampsia which is a life-threatening condition needs to be ruled out too.
Either call your doctor immediately or head to the ER or L&D. This is something that requires medication attention NOW.
I think halucinations are enough to see a doctor.....
