Prolactin levels?

Hi you guys. Just got my blood work back from the doctor -- my prolactin level came back as 27.4 -- I had to go back and re test today. Won't get my results back until Monday/Tuesday. Does my prolactin level mean it'll be hard for me to conceive? Could it be an early pregnancy level?!? Freaking out. 
I had dark brown spotting for four days. Then had a very light period for four days. (enough blood for a panty liner, not enough for a pad) dots here and there
