Should I retake pregnancy test? Only took 1...

I’m 19. My period is now 15 days late. I’ve been having cramping, nausea and breast pains on and off, I had unprotected sex on the 20th my period was due a day later. I’ve had sex again and it still won’t come. I took a pregnancy test while I was drunk but it came out negative. I looked it up today and it shows that alchohol can affect the test results. I tested 10/04. Should I retry and take the test again sober today? Or wait a few days and do it. Please let me know.
