Understanding Your Cycle
Ovulation usually occurs about 14 days before your next period starts. Your "fertile window" includes the day of ovulation and the 5 days beforehand, as sperm can survive in the female body for up to 5 days.
When should you see a doctor?
- If your cycles are shorter than 21 days or longer than 35 days.
- If you have been trying for 12 months (under 35) or 6 months (over 35).
- If you have irregular or painful periods.
