What Should The Cervix Feel Like At 13 Dpo I've Waited This Long... Should I Keep Waiting?

I've waited this long... should i keep waiting? - what should the cervix feel like at 13 dpo

Now I'm ... 12 or 13 DPO my period is expected to take place last night or morning. I want to test .... I do not, because it will finally start my period tomorrow. So wait, how I want.
But if I start tomorrow morning ... is a test taken in the evening, is it necessary? Or should I wait until the morning of Friday? I do not really try to find a right to a pregnancy, before to go to work. And I have tomorrow off ... What should I do?

My uterus feels weak and strong ... and my neck is a little higher, closed and command? Feeling that the sponge as usual feeling just before my time.

Was lower on Monday, then jumped back up there ...

You need to test yourself? Or wait?

What would you do?
