Yeast infection delay? PLEASE HELP

Okay, so Im freaking out.

I had intercourse with my partner two days before my ovulating day. Then several days later I douched (I was curious 😖).

A couple days later I'm pretty sure i got a yeast infection. Which is now better btw.

The thing is that my period is late now. And there's so many factors.

I already took three pregnancy test and they're all negative.

CAN SOME HELPPPP.
