natural pregnancy avoidance?

Charlotte
Hi, is anyone using this app to avoid pregnancy naturally? I'm 24 and have been on the pill for years! But after recently reading an article I want to come off and seek other options which are better for me and don't mess with the hormonal system. I've heard about people learning their ovulation cycles to avoid. Is anyone here doing this that could shed some more light on the situation? You would be a great help! Xx
