Pregnancy symptoms

Okay so we all get them and it's normal, but I feel like I read on apps and hear things from my home nurse such as "blank is normally but if it becomes servere talk to your doctor or let your doctor know" and everytime I mention something to my doctor she just blows it off as being "normal". I'm confused as to why I'm constantly reading things that says let your health care provider know, and when I do it's basically pointless I ever said anything. Am I the only one this happens to? Or am I the only one that it's annoying?
