Just about to lose it!Someone help please

9 days late for my period. I've taken 3 tests (2 clear blue) (1 Ept) All of them were negative. My breast and nipples are super sore, and I have blue veins on my breasts mostly near my nipples. I have very little to no Cm, I check my cervix daily and yesterday it was open and now it's closed high can barely reach it and soft but closed. Am I about to start my period, ovalute what? I'm out of answers and about to go crazy
