Should I test tomorrow?

I thought for sure my period was coming yesterday when my temp dropped, but it didn’t.

My luteal phase is usually 13-15 days and usually my temps are higher (in the 97.5 to 98.0 range) so that’s frustrating that they’re so low this cycle.

Peak day was 4 days before temp rise, which I’ve read can be common. I took a test 12 days after the temp rise (16 days after peak day) and it was negative.

I’m not sure if I should waste a test tomorrow or if I should just wait it out and expect my period.
