Frequently Asked Questions
When does ovulation typically occur?
In a standard 28-day cycle, ovulation occurs about 14 days before the next period starts. If your cycle is longer or shorter, this window shifts accordingly.
How long is a sperm's lifespan inside the body?
Sperm can survive in the reproductive tract for up to 5 days, which is why the fertile window begins 5 days before ovulation.
What cycle lengths are considered regular?
Most cycles range from 21 to 35 days. If your cycles vary significantly from month to month, consult a doctor for personalized monitoring.
