Bbt newbie question

Melissa

I just got an Ava bracelet so I started wearing it as soon as I got it. I didn’t bbt before so I don’t know my normal. So it was already 3 dpo from what my opk peaked and being able to feel the ovulation pains. My question is that my temps have been going down a little bit the past 3 days, is that normal? Does that mean that I’m out for this month? I know it’s not a lot of info to go on but in your experience if it continues to decrease does that mean I’m out.
