Just wondering if my blood pressure is low or high? It ranges between 100-110 over 60-70. Is this high/low/normal? I'm nearly 21, 6ft tall and had a pre-preg weight of 64kgs and now nearly 80kgs if that's needed at all..

The nurses say it's fine but was told the top should be 100+ur age upto age 30, and bottom should be roughly 100-ur age upto 30 for it to fall into a "normal range" which would make me 120/80?
