Weird period.

So I just had a weird period. Most of the time the first day is super light and I just need a liner and then it gets heavier, but for some reason this period never got heavier. The first day was light and then the second day (yesterday) there was only a lot when I wiped and that was it. (I was also super sick yesterday, which a bad stomach virus) and then today, I am not even doing anything other than spotting. Could this be normal??? Me period are only 3 days.
