I was looking at a new website today and started laughing at something I'd never seen before. They have a necklace that you can use to track your cycles so that you can see when you'll be fertile and either TTC or avoid getting pregnant. I've heard of some interesting ways to track a cycle, but a necklace was a new one for me. We use a paper chart as well as fertilityfriend, but I don't think I could do this.
What are some interesting or novel ways that you've seen to track a cycle?
