cervical position question

Ok, so I just started checking cervical position a little over a month ago. I've gotten a fairly good idea on where it should be, I used to check every so often when I had the Mirena. So I ovulated early and it had SHOW for sure. Right after that it was as low as it has ever been, like even my hubby could tell (TMI I know). Anyways, 2 days ago it was low, firm and closed like it should be at 7dpo. Then it softened up a bit yesterday but didn't move. Today i was shocked to find it is high, soft and closed! Huge change from yesterday and I want to know should I get my hopes up. I am 10/11dpo and I don't get AF till the 21st (I ovulated early). I'm seriously trying to wait to test... 😩😩😩
