94/68 is a good blood pressure; 94 is the systolic number and the 68 is the diastolic number. Now, if you diastolic number goes significantly down then I would worry, but as it seems it looks good; a lot of people would love to have that blood pressure. All people are different and run different blood pressures, you just need to find out what is normal for you. Take it everyday for a week and if it doesn't change too much then that is most likely normal for you. My blood pressure also runs low, it's a good thing, trust me.
