11 days late

Hey I’m 11 days late for my period now, had a faint positive at 10dpo and then started getting negatives, so chalked it up to being a chemical??!! But now I am 10 days late lots of clear cm and white cm, cervix is stitch closed and soft, lots of symptoms, haven’t really paid a lot of attention to anything u til today when I’ve noticed I’ve still yet to start my period. I don’t know what’s going on but I’ve never been this late before and so any comments will be appreciated thank you
