My Blood Pressure Is 103/ 47 Pulse Is 64 It's

My blood pressure is 103/ 47 pulse is 64 it's always around this range or top number in the 90s . I have asked my Dr my heart Dr but everyone says it's great ? I'm a 50 year old female don't eat any meat except occasional rotisserie chicken . I do a lot of walking exercise regularly ? Everyone I know has high or on high blood pressure medication . Could something be wrong ?
