Invisalign + Irritation Q&A

I just got Invisalign two days ago- the dental assistant was very sloppy with the bitter tooth conditioner and it seeped under my gumline. My mouth became very irritated and sensitive! I have no idea what to do- there is now exposed soft tissue from my tooth that is excruciating to brush over. Both examples are highlighted in the photo. I don't even know who to call to fix this- any advice is greatly appreciated

I am on tray 14 and have never experienced this before. There is irritation in the space between 2 teeth and when I remove the tray, it bleeds slightly. I am not sure if this tray is defective or if this is normal. I can not get in touch with my orthodontist until after the holidays and I don't want to continue to wear it if it is causing damage.

Are there any over-the-counter medications available to help with this?

This is the 2nd day I am wearing invisalign. A part of my gums is red, irritated and sore. It looks like its bleeding but its not. What does this mean and how can i treat it?

I started using the aligners 48 hours ago. The inside of my mouth seems quite irritated, especially the inside of my cheeks. Will this subside? The expectation was set that I would have this for about a year. I have 21 sets, which would tell me 42 weeks. Any reason why this is off? Is it possible to accelerate the schedule? Also, any chance I can change out the trays faster than 2 weeks if I keep diligent logs calculating actual time wearing the aligners?
