Could this be early pregnancy sign?

Sa

My menstrual cycle started from 3rd of July, and predicted to have 28 days this cycle. I started seeing EWCM at CD 14, immediately after having intercourse. I’m currently 6dpo (according to OPK that tested positive on 15th of July (my only assumption came from immediate flashing smiley face on Clearblue Digital Ovulation Test after putting the test stick because I ejected it too early, and I couldn’t do the test again as I ran out) but I have this discharge. Can it be possible for me to have conceived? Bear in mind there was no insemination. I had the same symptom last cycle but I had my period.
