when is the most fertile time in my cycle?

• The most fertile days in your cycle are the days leading up to ovulation; this is referred to as your fertile window.
• The egg can survive for about 24 hours after ovulation, while sperm can survive for 2 -3 days in the fallopian tube.
• To give yourself the best chance of conceiving you should be having unprotected intercourse every 2 -3 days during your pregnancy window so sperm is already present in the fallopian tubes.

What if my cycles are irregular?

• If your cycles are irregular or your cycle length varies from month to month it could be difficult to calculate your ovulation date and fertile window.
• Ovulation urine tests or ovulation cycle tracking may be useful and you should seek advice from a specialist.
