Anyone who gets done Acrylic and liquid gel nails

Hi everyone, I am writing because I am a bit nervous about my nail. I have never gotten my nails done before but did recently for my wedding as I did not want to press on nails just in case one fell off. As I was cleaning on Sunday one of my nails broke off I noticed that there was little black dots or tiny little short lines. I am freaking out. The place I went to was recommended by my cousin she goes there all the time and gets her nails done all the time. Has this ever happened to anyone? I am unsure if it’s on the outside of my nailbed or the inside? Please help! I am so nervous!
