What happens to cervix between ovulation & conception?

So I’m seeing a lot of different information online. I know at the time of ovulation your cervix should be higher and feel soft.

If you conceive during that ovulation time, will your cervix return to its normal position and feel hard again before implantation, and then when implantation occurs go high and soft again?

Or will it just stay high and soft before implantation has occurred?

I can’t seem to find an answer anywhere. I’m assuming it’ll return to normal / hard and then go soft again as otherwise wouldn’t people use that as a fairly reliable indicator of pregnancy?
