Does anyone check there cervix after ovulation?

Does anyone check there cervix after ovulation and from what u learned that ur cervix should be high if pg, and if it low that u just automatically assume ur not pg because of a low cervix? Because it says if it stays high then ur pg, if it's goes back down (low) ur not pg? Just wondering if I still have a chance, my AF doesn't come until the 19th...
