AROUND THIS TIME
Energy and cervical mucus often pick up in the fertile window. Some people feel a twinge. Many feel nothing.
Estimates aren’t medical advice. For health concerns, talk to a clinician.
Understand your fertile window.
Logged period is a solid pink circle. Predicted period is dashed. Fertile days are teal. Ovulation is a ring, not a blob.
Fertility predictions are estimates and should not be used as a substitute for medical advice or contraception.
