Blood pressure question

So I went to the doctor two weeks ago and my blood pressure was 130 over something which is weird because normally it is like 115-120 well I started swelling really bad and getting headaches not bad ones so I went and checked my blood pressure and it was 134/79 which isn't high but I checked it tonight and it was up to 137/77 which means it's elevating. Is this normal or has anyone else experienced this? I have an appointment Tuesday but just wanted some words of wisdom now. I'm 34 weeks.
