Confused

I'm so confused. Glow told me AF was supposed to come on the 21st. I have anothe app that said the 26th. Still nothing. I tested twice but they were negative. I did test the 21st and it was a cheaper test so maybe I'll try again since I'm a week late? Ugh. I am having some symptoms like I did my last pregnancy but everyone is different! What should I do??
