Confused TMI please offer advice! :)

Usually i ovulate around cd12 i was told not to use opk this month bc it may not be accurate.  I took clomid cd5-9 i am now on cd21 and have slight symptoms i think.. but it could be af... Well i just went to the restroom and i had some ewcm? Not much, but some... Could this be a pregnancy sign??  What could this mean???? Any ideas are appreciated!
