Understanding Ovulation and Fertility
Ovulation is the phase in the menstrual cycle when an egg is released from the ovary. This is the most fertile time in the cycle.
Key Facts:

- Fertile window lasts a few days before and after ovulation
- Sperm can survive for several days in the reproductive system
The calculator uses this biological pattern to estimate pregnancy chances.

Very High Risk

High Risk

- Strong chance of pregnancy
Medium Risk
- Outside peak fertility but still possible
Low Risk
- Far from ovulation
- Lower probability of pregnancy
No Risk
- No unprotected intercourse reported
