Beginner please help me

We have been ttc for 6 months first couple of months I used opk’s and then thought I’d take the relaxed approach and see if it happens on its own...it didn’t 😭. So I’m thinking now I need to try bbt aswell?

Can someone please explain to me in a real dummies guide on how to read/use the charts as when I look at other peoples it confuses the hell out of me how you know when you’ve ovulated etc

Sorry it prob sounds really dumb but I can’t take another month of negative tests.

Thanks in advance
