⚠️ "Safe days" use the calendar method — a prediction, not a guarantee. It is one of the least reliable ways to avoid pregnancy, and it is unreliable for irregular cycles, after childbirth, while breastfeeding, or when stressed or ill. Do not treat it as contraception you can count on.
Not enough regular history yet: needs 3+ logged cycles, all 26–32 days long, before "safe" days mean much.
