What does this mean?

I got my peak at 6:36 on CD 18, we BD at 5:30am on CD 17. I literally had every sign of ovulation with CM.. I'm pretty sure I ovulated on CD 19 since my CM was really watery, and the next day it was dry/heavy creamy.

Took my temp this morning and of course it dropped. I'm just feeling defeated at 2 dpo🙄.

Any opinions about my temp dropping are much appreciated, and if this means I'm out this month?
