Bbt help

Natalie

So I honestly don't understand how to track BBT and what it means, could some of you ladies explain a couple of things to me to help me understand please?

1) am I supposed to track it every day of the month

2) what SHOULD it show if I've ovulated

3) does this differ with PCOS?

4) how do I know if I'm coming up to ovulation/actually ovulated etc?

Thanks in advance beauties
