No! Not bad at all! Students do it all the time!
A lot of times students go into college thinking "this is what I want to do" and then find out that's not it at all. Or, maybe they take a class that ends up sparking an interest in something they didn't know existed, got involved in a student group that inspired a committment to a cause, etc.
If you'd need to change your major, go straight to your college academic advisor and talk about the ways you can redistribute your existing credits into a new major. Or, consider adding a minor.
Today's work world is what is called a "gig" economy. People change jobs all the time. It's ok to expect your interests to change, it allows you to build more skills.
As far as making decisions about what careers might be a good fit for you, I suggest you take a look at O*Net. It's information from the department of labor. It gives tons of great information about careers/jobs including what skills are needed, education, what the tasks look like, how much they make, and is it a growing field in the next 10 years, etc.
Make use of your college's career center. They can help you clarify your goals, point you to opportunities for internships in fields you're considering, and review/advise on your resume and cover letter. The Career Center is designed to help ALL students, not just seniors. The sooner you go the better.

You should change your career direction when you find that the existing one is not appropriate. You do not want to end up in a career area for which you are not well suited. However, before making a change, it is very important to get to know yourself better to determine if the new one fits better and talk to people involved in that career area to see what they do, how they got there, and what advice and suggestions they may have - and how you feel about it.
Getting to know yourself and how your personality traits relate to people involved in various career opportunities is very important in your decision making process. During my many years in Human Resources and College Recruiting, I ran across too many students who had skipped this very important step and ended up in a job situation which for which they were not well suited. Selecting a career area is like buying a pair of shoes. First you have to be properly fitted for the correct size, and then you need to try on and walk in the various shoe options to determine which is fits the best and is most comfortable for you to wear. Following are some important steps which I developed during my career which have been helpful to many .

You have been given some excellent advice already. One additional thought to consider is to gain insight into your true strengths. My favorite assessment is StrengthsFinder. It will not only identify your true strengths, it will also provide insight into the potential educational and career options that are commonly sought with those strengths. This along with the other resources you've been given will provide a well-rounded solution set for your decision-making process. Best of luck.
