🤔 Frequently Asked Questions
Can I get pregnant outside my fertile window?
It’s less likely, but not impossible. Sperm can live inside the body for up to five days, and ovulation can vary slightly each month.
What if my cycle isn’t regular?
If your cycle changes often, try entering an average number of days. Tracking for a few months helps you notice your personal pattern.
Do I need to use the calculator every month?
You can if you want, but your saved data stays here! Reuse it anytime or update the date if your last period has changed.
Can I use this calculator if I’m on birth control?
The calculator won’t reflect accurate results while on hormonal birth control, as it changes your natural ovulation rhythm.
