AF due 10/10

Clarissa
My AF is due 10/10 but she hasn't shown up yet I took a test on the 10th and 11th but they were all neg. right now I have really creamy/ sticky CM. is there a way I could be pregnant? Even though the tests showed up Meg or has anyone else had these symptoms and started their period late? Also my cervix is at the point I can't even reach it anymore.
