HELP!

Katie

I’m four days late on my period according to the app, my period is super irregular, had unprotected sex with two different guys November 9 & 10th. I’m not on birth control and didn’t take plan b. Took a pregnancy test last night it was negative however this morning another line showed up saying I was pregnant. Freaking out I took two more tests today and they say I’m not pregnant. I made an appointment at the doctor for a pregnancy test but it’s on Wednesday. What should I do? Just wait it out or keep taking tests
