Checking your cervix position is a bit different than checking your cervical fluid. When you check your cervical fluid, it is recommended to check several times a day and note your most fertile fluid of the day. The cervix, however, may change position depending on the time of day. It is usually higher in the morning and lower in the evening, but your own experience may vary. It is thus recommended to choose a time of day to check your cervix and stick with it throughout the cycle, recording only the observation from the usual time.
