Generally ovulation occurs in between 12 to 16th day of each cycle, but the day may vary depending upon the action of hormones.
The day of ovulation may not be same every cycle,
So, your efforts should be, from 12 to 16th day.
Major factor influencing the whole reproductive cycle is ‘once mental health’
& All cycles may not be reproductive cycles.
