Cracked Invisalign Aligner?

My lower aligner is busted. Not completely, it’s a got a crack in it which means the aligner isn’t as snug on my back teeth as it should be.
First, I think I cracked it because I got 3 buttons put on my bottom teeth and it’s tough taking that aligner out with those on. It always feels like the thing is going to break when I take it out. Anyone else have those buttons on and know an easy way to take the aligner out? I try and get the back part off first but it’s tough and I feel like I’m pulling it and bending it too much.
And then, my dilema is should I call the orthodontist? I really don’t want to pay for a replacement aligner. I’ve heard they’re kinda pricey. I’ve had it in a week. Is it possible to just go to the next aligner if it fits and then wear that for extra time? I’m just worried that the next one will crack too and then I’ll have 2 cracked aligners. To call or not to call?
