Do we have egg white cervical mucus on ovulation day

Tired of TTC

Hi friends,

Please advise if you see egg white cervical mucus on ovulation day..I see fertile slippery mucus on day 10 to day 12 and it gets dried later. My cycle is 30days and my probable ovulation day as per OPK and ultrasound is day 14 to day 16th.. please advise how to increase CM naturally..
