**Sorry it's long I'm super confused and concerened**

So I've had a headache with little to no relief for the past two days (9/24-9/25). We go to my regular OB check up at 4pm on 9/25 and my blood pressure was 138/92. My doctor expressed concern being I'm usually more like 110/70. They ran my urine and it comes back negative. They've now checked my blood pressure twice and it hasn't changed. My doctor told me to go home and relax and to come back Friday 9/28 for a recheck or if my headache got worse to go to L&D. Well hubs is a fire fighter but off duty today. When my headache got worse we headed to the fire station just to check things. Well my blood pressure shot up to 156/98 so we go ahead and head to L&D. We get to the floor about 30min later and my bp is perfect starting at 120/80 and down closer to my normal at 111/68. They discharged me and now the headache is back. Anyone have any experience with headaches and high bp?
