Bp reading fluctuating -35+5 days pregna

Hello, Everyday I take my bp readings before I go to bed or in evening, last night I have been finding spike in my bp readings in electronic machine, initially it showed 145/94, later on after sometime I checked it was back to normal then by 3 am again I checked it was 138/84, so I started worrying I have never checked for so many readings, so we went to hospital to check my bp manually, which was 130/80 when we checked there, following that general physician said it's normal, now in morning I am again checking my bp it's 138/83, I don't know what to believe please doctor help me, I have my checkup today with doctor, do I start with bp medicines? I am worried a lot, I never had bp problem in entire pregnancy till now , please help me what should I do?
