CD 38 No symptoms, No AF

Friends, Today I am cd 38th, I have no symptoms at all, still no AF. I usually have 32 /33 day cycle sometimes 35 days too when I take clomid/letrozole but I saw my history I havnt got conceived whenever I was on those mess. But conceived when I havnt taken anythin. I haven't tested yet thinking it might be delayed bit now i am worried. I haven't taken any medicines, no clomid, no letrozole no metformin nothing. So may be cause of that my period is delayed. Today I saw some white discharge when I was wiping, not sure if it's sign of AF coming or maybe pregnancy. I am gonna test tommr morning now. What do you all think? Is it possible to be prego with no symptoms? Is white discharge sign of AF or pregnancy? Please pour your thoughts
