From what I read on social media, it seems there's still a lot of controversy surrounding Natural Cycles and before I signed up I wanted to talk to someone who used it but didn't know anyone.
I'm not a gynaecologist but can at least answer questions on my personal experience with it if that's helpful to anyone...
And purely for transparency - I do have a referral code that gets you a free thermometer and possibly a discount on the yearly subscription (I think, please don't hold me to that), I get a little achievement so there's no monetary gain in it for me whatsoever. Basically I don't work for them and I get nothing of any value so it's purely to help anyone that may be thinking about.
