Hi.. Past two three months my periods are irregular... Sometimes 30 days cycle sometimes 35 this time 40 days... In that how can I calculate my ovulation period.. For example if 20 Jan is first day of my period when will be fertile days for me to conceive?

A. We cannot calculate based on the days as it will be accurate when the cycles are regular for at least 6 months. You can start having intercourse as early as 10 th day of the cycle for alternate days atleast until 40th day and do a pregnancy test after that
