Help with BBT charting?!

Angela • 💍 💙

Ok so, I just started temping today. But I am still a little clueless...

In order to assume ovulation, your temps have to spike up for 3 days, right?

Do they go back down after ovulation? Or do they go up?

Can anyone explain this or any other things to look out for? Please?!

Like I said, I just started today. So I want to be sure I know what to look for.

Thanks everyone😊
