5 days late & no BFP

According to the app I was suppose to get my AF on Friday. I've taken a number of test, including one today and nothing. I was cramping on and off and had slight spotting (only when wiping). I don't feel very different. I'm just confused, I don't want AF to show up but I would like to get a positive pregnancy test already. My period has always been on time. I'm worried maybe I'm just stressing myself too much ttc and my af isn't showing up :( just want to see a positive test already Lol
