Clear Blue Fertility Monitor Thoughts??

Melissa💗 • Rainbow baby born in 2016, then another miracle born in 2018! 🙏🏼 Currently just found out pregnant with baby #3! Fingers crossed all is well! ❤️
Stumbled upon this fertility monitor today & was intrigued! It's very pricey though & the #reviews have been mixed 🎭 Anyone have any reviews or thoughts to help a fellow #ttcsister out?? 😀❤️
