Cervical mucus

I just started ttc recently and I am 9dpo and af is due in 4 days on the 10th. I had sex on the 2nd and 3rd and yesterday. Tonight I noticed I had a thick white creamy like cm and am wondering what it could mean? I’ve been very tired lately and got nauseas at work over foods that normally don’t make me feel sick and I’ve been having headaches. Possibly pregnant? Pictures below sorry if it’s TMI
