it could be hérna with means here and it is very common in icelandic. for example: hérna er maturinn - here is the food komdu hérna - come here (we sometimes say it when we are thinking, before we are asking question)

well I am just learning too but here are my two guesses. "héðan" an adverb meaning "from here" "hérna" an adverb meaning "here" which is commonly used as a filler word. while both words are quite frequent hérna certainly appears more often so it is probably that one.
