Advice please! New to bbt tracking, at 13dpo.

I'm 13 dpo (confirmed using opk's), only recently just started tracking bbt. Usually when I'm getting my period my cervix is extremely high and CM is brown tinged. I'm due tomorrow and my cervix is extremely low to the point I can't even get a whole finger in, literally the tip and varies through the day of soft and firm.

I did a test at 9dpo and it was extremely faint (pictured) and is pink in person.

Could I be pregnant or?
