My understanding is Ovulation is from 14days from the 1st day of your menses. When i went for a full body check up, the doc told me beside counting the days, i should look at my discharge. If it is transparent, clear n sticky means you are ovulation! I suggest from Day 12 to Day 18 look at your discharge.
I followed the doctor advice and that's how i got my baby boy
Good Luck to all who are still trying
