Just a quick one, something i've been worried about

I'm on my 8th week of treatment this week, and haven't had an adjustment yet as my ortho keeps cancelling on me, but should deffinitely be this Thursday woohoo! I've noticed that the wire on my back teeth has suddenly got loose and is resting above my tooth now like by my gum.
Could this be due to my teeth pushing and the wires too big for that space or something?
I've been really careful with what i'm eating, and been making sure i'm cleaning them well, so just worried incase I get told off for something i'm not aware of.
Thanks for any help
