Flo has been great for me in a long time. It keeps me on track on my period and my health overall. It’s your assistant in your menstrual cycle, before menstruation and after. It is always there to help you know more about yourself/body, when to conceive not being able to conceive. It is like your home doctor and always there to care, support and remind you on everything concerning your body. Flo is a life saver! ❤️💖💕
