Should I be worried?

My period is now 5 days late, should I be worried? My fiancé and I use condoms and we always check during sex to see if they are still in tact, which they always are. We're really careful, I honestly don't think at all that anything could've happened for me to get pregnant. I've got really sore boobs (which I get when my period starts every time), have been hormonal and have had a few cramps the past few days but no period yet and it's just weird how late it is. I dont think I should be worried but I have anxiety and can't help being worried 😂is it worth testing? I also skipped my period entirely in August for no apparent reason so I'm not too surprised
