Help!

Janey • This frikkin` lady.
Alright, ladies, I am at a loss. I used to have periods that started right on the dot, like clock work, even after three babies, and now that I've started tracking all of this, I end up being a couple of days late, then to test negative, then start AF
Last month I had an infection in my foot and it managed to delay my period for a week. 
Now, my period should start Friday/Saturday, yet my cervix is still high, soft, and closed, when it usually drops and/or at least I can feel a nub? I don't want to get my hopes up, and/or test early as I've seen WAY too many negatives at this point, however, what would be your take??
