It’s not for natural birth
It’s not for natural birth control it’s only to give you insight on where you are in your menstrual cycle . You can do this all by yourself you don’t need this to tell you what you already know about yourself. There’s nothing special about tempdrop it’s not FDA approved . They tell you you can use it for natural birth control to reel you in but when you buy it they tell you they truth . It’s basically a toy . It’s not worth an investment. I stopped using mine .
