Wearing Invisalign trays only at night?

Hi, so I recently started invisalign, and am on my second tray. I won't be seeing my orthodontist until 2 1/2 more weeks, but I would already have been wearing the same trays for 14 days this Friday (he told me to wear them for 10). I do not have anymore trays yet because he wanted me to get attachments. The office told me to just wear my trays at night until the appointment, but come in with them. Does that sound like a good idea or should I just keep wearing them?
