About Natus: Fertility Journal
Understanding your menstrual cycle starts with observation. Natus is a private natural fertility journal designed to make recording your cycle simpler, clearer and faithful to what you observe each day. No automatic predictions and no determination of fertile days or ovulation. Natus organizes the information you record so you can follow your history with clarity. With Natus, you can record: • sensations and appearance observed throughout the day • cervical mucus and bleeding • menstrual cycle information • chart symbols and markings • intercourse • symptoms and medications • basal body temperature • saliva crystallization • personal notes TRACK YOUR HISTORY View your records in clear charts, follow your observations throughout each cycle and keep your history in one place. TRACK TOGETHER If you choose, share your tracking with your husband. This allows both of you to take part in recording observations and follow the same journey with greater closeness and organization. TRACKING WITH AN INSTRUCTOR You can also invite an instructor to follow your records, making individual follow-up and guidance easier. REPORTS Generate clear reports of your observations to save, share or use during professional follow-up, including MOB-format report options. NATUS PREMIUM Essential recording features remain available for free. Natus Premium offers additional features, including tracking with your husband, tracking with an instructor, basal body temperature, saliva crystallization and advanced reports. PRIVACY AND CONTROL You remain in control of your records and decide when and with whom you want to share them. Natus was created for those who want to observe their cycle with attention, consistency and clarity. Your records tell a story. Natus helps you organize it. Natus is a personal recording and tracking tool. It does not provide diagnoses, determine fertile periods, prescribe treatments or replace medical advice or advice from other healthcare professionals.
