High blood pressure jump 30 weeks

Chelsea
So I just had my doc appointment. 2 weeks ago my blood pressure was 136 and today it was 150. I had blood drawn and told if I have a migraine to go to the hospital immediately. I was tested for preclampsia a few appointments back and came back clean. Any thoughts on this? I was moving heavy furniture yesterday and walked up a bunch of stairs before my appointment. Has anyone had their blood pressure jump like this? Baby seems fine, she's head down and measuring well and good heartbeat and kicking.
