When your period is over should the cervix be high? Or low?

I've scanned a few articles online but am still getting the hang of feeling my own. My period ended 3 days ago and my cervix is high but according to glow I'm not due to being ovulating till the 14. Shouldn't my cervix still be low? I had sex the last day of my period knowing the risk would be very low. But now I'm wondering if i'm ovulating early. Any masters of their cervixes out there?
