Cracked iPhone back

A few weeks ago I got my charging port fixed third party on my 15.5 month old iPhone 11. Now the back glass has a small crack on one of the sides.

There is no glass coming out. However I’m concerned that this could get worse. If I leave my phone in the case (hard case) will it make it to 24 months so I can get an upgrade? My battery life is 86% as well, and I have a very small pressure spot on the screen from the third party replacement, but none of those two other things are affecting my phone at all.

I have never had an issue with an iPhone until this 11, which won’t stop breaking. I know that glass cracks on the back can get worse over time but mine isn’t too bad. I don’t want to tell my parents as they’ll just get mad and I know that apple can’t fix a cracked back.

Is this anything to worry about or will it likely be fine until I can upgrade?
