Can BP be too low without symptoms?

I'm planning on ralking to dic about this when I go in later this week, but at a work place health screening earlier this week, my blood pressure was reading "something normal over / 49". 49??!!  
I don't have a history if low BP, very healthy overall, healthy BMI prepreg and on track with weight gain, I feel like I always do/always have (sonothing  "feels" out of the norm...) I tried googling healthy BP ranges but couldn't find anything - So, is lower BP really fine as long as there are no symptoms?
