HELP PLEAAASE ?!

Hi guys, I'm needing a bit of advice please. I am due AF on Monday and I always come on a few days earlier than glow says. I always also get very sore breasts and bloating for a week before but this month I haven't got any signs it's coming but also not really had any signs I could be pregnant except a headache and being quite tired. I just wondered if anyone else has NOT had their usual pre-period symptoms and ended up being pregnant? I stupidly tested 2 days ago which obviously came out negative so I'm going to wait and see if AF shows before testing again. Just curious to see if anyone else has had this before? xxx
