Unless you’re one of those lucky couples who has sex 2-3 times a week, you’ll want to work out the best time to optimise your chances of conception.
Keeping a record in a diary or app of when your period starts, how long you bleed for and how regularly your period comes will help you determine roughly when you should be ovulating (and therefore having sex).
Usually, if you have a regular monthly cycle that lasts 28 days, ovulation will occur 14 days before your period starts. We generally advise having unprotected sex every 2 days from day 10 to day 16 of your cycle, to cover that ovulation window. Statistically, 24 hours before you ovulate is the best time to have sex for conception (once an egg has been released from an ovary, it can survive for 12-24 hours, while sperm can last up to five days). If you’re trying to work out your cycle length, take the first day of your period (day 1 of your cycle) and count up until the day before your next period starts (the last day of your cycle). This number is your cycle length and it may vary slightly from one month to the next.
Additional ovulation signs can be helpful to track such as measuring your basal body temperature or checking for egg white discharge (a fluid that has an egg white tint to it). Some people prefer to use ovulation sticks. These check your urine for LH surge (luteinising hormone surges 24-48 hours prior to ovulation) and will indicate the peak time to have sex. For best results, use it during your first pee of the day.
