Newbie here.... BBT

Kell

So I have never tracked my bbt. I've only tracked my ovulation with ovulation test. Is tempting hard? Has anyone had any luck doing it? Is it worth my time? Honestly seems like a lot of work... But next month will be 4 months ttc and I want give it a try. So any advice would be greatly appreciated!!! How does it work lol. I know nothing about this
