I have an open bite/underbite as my canine is moving. What should I do?

I'm getting treatment for an open bite with elastics and braces. For a couple weeks, my elastics have been on my bottom canine and around my top premolar and top canine(upsidedown triangle). This has been slowly closing the gap but now my top canine is coming behind my bottom teeth(like an underbite). My ortho is in Italy for 2 weeks and I don't know what to do. If I continue I fear my top canine will go even more behind my bottom teeth. What should I do? Is there another way to put my elastics?
