!!!!Please help!!!!! Late period

Okay so my period is late and I'm not sure why... It's late by about 5 days although sometimes it goes completely off wack anyway...

I haven't had unprotected sex since my last period and I also didn't have sex during my fertile window and all condoms used had no breaks.

I have been pretty stressed but the weird thing is that I have had no period symptoms, usually I get sore and swollen boobs, bloating, cramps and mood swings but this month I haven't had any of that.

I am so confused because I don't see how I could be pregnant but I don't know what else could be causing this...

Please help 😊
