13dpo cervix?! PLS HELP


So i woke up having to pee really bad and decided to check my cervix.1dpo-10dpo it was high and soft and slightly open, 11dpo it was low soft and open (i lost hope when it was low), and the next morning (12dpo) it shot up high to where i can barely reach! Today(13dpo) its tilted towards my tummy! Its open and its very soft. Ive been having all real symptoms (definitely not made up in my head) AF STARTS TOMORROW BUT NO SYMPTOMS OF HER! I took a test 11 and 12 dpo and both were BFN :( was also a little too early to test. Someone ever get a BFP with a cervix like this? Or get a BFP after 12dpo?
