How does one know when the probe is in the right place?
to top The probe should be inserted until a slight resistance is felt, which is when the probe just reaches the cervix. This is approximately 3/5ths of its length. (Ie: 3 inches in the bitch and 2 inches out showing). At this position the probe tip is positioned within the area containing the maximum amount of mucus to thus obtain accurate and consistent readings. This position is adjusted slightly relative to the size of the bitch. Also some bitches are very dilated early in the cycle with little or no resistance being felt. However the 3/5ths positioning still applies.
