It works!! - Love is an understatement! After a year of trying with my hubs and an early stage miscarriage, we got daysy. I had it 2 full cycles before successfully getting pregnant!! Previously used a tracker app and it just wasn’t tailored enough to me to be effective. Daysy truly changed the game for us! 15 weeks and counting ❤️ Review: DAYSY WORKS! - I honestly DONT know how anyone can have an issue with this device. Those who do either didn’t read the Manual so the learning curve must seem steep or miss temperature days which is the whole point of how this device predicts. I’ve only had this device for two months and already it is MIND BLOWING on how accurate it is. I do manual FAM charting to cross reference and to be safe but each time it matches DAYSY’s predictions. Please go on the DAYSY website BEFORE buying to determine if you are compatible with this device. It helps more to have a consistent cycle. READ THE MANUAL!!! It helps to understand the button faster, its colors, and rules on exceptions. Watch YouTube videos on DAYSY reviews and instructions to understand the device. I will say that the app was annoying on the day I set up the DAYSY(syncing issues). So If you are not a very patient person or if you try to do it on the go, I can see how you can assume that it’s not working. But since set up( which took an hour or so) it has run smoothly. I have forgotten to put in my period and gone back the day after to do so. I’ve also put my period on the wrong day accidentally and corrected it very easily. Correct things as soon as possible. It’s not a magical stick. You need to give a bit of attention and consistency to get the most out of it. ## Features - Take Control of Your Fertility with Daysy: A hormone-free, precision fertility tracker.

Había leído quejas por la tardanza del dispositivo en darte más días verdes (que son los días seguidos para mantener relaciones sin embarazo). En mi caso que soy irregular y solo llevo un ciclo, ya me ha detectado para este mes 11 días verdes. En Europa es considerado como un dispositivo médico. Tiene una fiabilidad del 99.4%, una pasada, teniendo en cuenta que no hay hormonas que dañen tu cuerpo. A día de hoy, estoy completamente segura de que hice bien en invertir ese dinero. La tranquilidad que te da, el tener tu cuerpo libre de hormonas si no quieres un embarazo, o al contrario, saber cuándo es el momento en que estás ovulando para buscar un embarazo. Incluso es capaz de detectar un embarazo por la temperatura. Claro que tarda aprender el patrón de temperaturas de tu ciclo, ya que cada mujer es distinta. Vivimos en una sociedad en la queremos todo para ayer, y hay cosas que merecen la pena tirar de paciencia, el porcentaje de fiabilidad es altísimo, hay que tener en cuenta que los años fértiles de una mujer, es un tiempo prolongado en nuestra vida, y merece la pena unos meses de testeo, a cambio de la fiabilidad que ofrece, tanto si buscas embarazo, como si no. Cada mes que pase te va a ir poniendo más días verdes. Yo solo puedo recomendarlo, lo único que me apena, es no haberlo descubierto hace años... ## Frequently Bought Together - Daysy Fertility Tracker – Natural Hormone-Free Ovulation Monitor & Fertility Awareness Device – Smart BBT Thermometer with App for Cycle Tracking, Conception, or Pregnancy Planning – FSA/HSA Eligible - Taking Charge of Your Fertility, 20th Anniversary Edition: The Definitive Guide to Natural Birth Control, Pregnancy Achievement, and Reproductive Health --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/137275356-fertility-tracker](https://www.desertcart.ec/products/137275356-fertility-tracker) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-20*
