new to this - no idea what's going on!

My last period was the 27th - 31st August, according to Glow AF was due on Wednesday just gone.. it's now Sunday and it's still not here. I've bought a test to take in the morning because I'm never late and I usually get AF when Glow suggests I will so it feels weird! But I haven't got any symptoms of AF being due like I usually do or any pregnancy symptoms.. what do you all think? We've been trying since June so I'm new to all this!
