University of Buffalo Changing Major Before Enrollment

I was accepted into Buffalo’s nursing program, yet I am now having doubts about studying nursing and becoming a nurse, I have a feeling that it just isn’t for me, and I am now heavily considering switching into Buffalo’s Speech and Hearing Science undergrad program on the path to eventually become a Speech Language Pathologist- a job I think I would enjoy more.
My question is, how would I switch my major now? From what I see online, the Speech and Hearing Science undergrad program has a separate application. I am worried I missed the deadline…I am not sure what I would do if that happened. I will call or email the department, but I also wanted to hear if anyone had anything to say about this first. Also, any information on nursing vs. speech language pathologist, or any other similar careers is definitely welcome! With May 1st in less than a month, I have to decide very soon…I’m definitely stressed!
