16 dpo?? Cycle day 30

Soon I was expected to get my period yesterday according to period tracker and glow but I didn't for days ago I had white cm on my underwear. Yesterday my bf and I had sex and when he was going to go down on me (sry huge TMI) he said my vag. Was really wet and at a point looked like white at the same time... If I was supposed to get my period yesterday shouldn't the cm look already caramel colored much less red? Idk what to think cuz I'm going on my second day of a missed expected period and I don't feel any different except irritated sore nipples...(again sry TMI)..... any input would be great (^~^)
