Cervical Position

India
Is cervical position a good indicator of pregnancy??
I know that it's supposed to be high soft closed if pregnant but I'm not sure as to whether this happens immediately or if it takes a while.
I've also read that your cervix will become lower and gradually get harder following ovulation. This can be a few hours after to a couple of days.
Mine has stayed high and is soft and closed.  I normally check every morning around the same time after BM (tmi sorry) but today I'm obsessing and it seems lower than when I first checked this morning. I'm 10 dpo today with negative cheapie. Should I be discouraged or not put too much weight on it?
