Those readings are pretty good- a little low, but decent. The thing to remember is when testing blood pressure you should always do it three or even four times - I do two standing and two sitting. And then average it out. Because blood pressure can change within just a few seconds to a min, and also between sitting and standing. My GP always does three in a row, and if its up, has me sit and relax for fifteen min, and then do three more.

Also a good idea to keep doing that each day for a couple of days!
