Missed period & yeast infection??

Ugh ok, so I had unprotected sex 3 weeks ago. Pull out method (I know I know) so my period is due. I got PMS, cramps, all the symptoms. But also...I have a yeast infection!! It’s going away slowly took some meds but I am also spotting a tiny bit. Kinda reddish light pink. Got worried took a test...came back negative...next day took another test...still negative. Am I okay???

I have been stressed a lot lately but idk. My period always comes on the day or a lil before
