Your Fertile Window
If you’re a woman who has regular periods, call the first day of your period ‘day one’. Typically, you will ovulate between day 10 and day 16. If you have unprotected sex across these days, you give yourself best chance of conception.
Don’t let the timing of ovulation become a source of stress. You only need to know the exact day of ovulation if you want to time intercourse to the day. If you simply have sex every day across the days you may be ovulating, you have the best chance of becoming pregnant.
