Is it to soon to test???

My AF is due Feb 5th. I have been experiencing spotting for the past 6-7 days; sometimes it is light pink, red and brown discharge. It is not all day just sometimes when I wipe and in my panty liner. I have also been very fatigue the last two days to were I need to take a nap (I never take naps during the day). I have also had dry mouth and hot flashes. Am I experiencing early pregnancy symptoms? Should I take a test or is it to early?
