About FertiCycle
Free tools to understand fertility and track pregnancy — in French and English.
This information does not replace medical advice. Consult a healthcare professional for fertility or pregnancy questions.
FertiCycle answers practical questions: "When am I fertile?", "What is my due date?", "What happens at week 20?"
Calculators use common clinical rules (ovulation at cycle day −14, Naegele's rule). Week-by-week pages are educational reference points, not diagnoses.
