High blood pressure???

My blood pressure usually averages 120/80 (which I have always thought was great). A couple of OB appointments ago my dr told me we need to monitor it because it may rise, next appointment after that it had went up to 130/83, I was concerned but he said it was fine and I shouldn’t need to be on meds... fast forward a month and my blood pressure is anywhere from 130/85- 145/95.... should I be concerned or is this ok?? I am in my third trimester(29 weeks).
