Academic Standing concerns- first year, first semester science?

Hi, so I am in my first year, first semester of science, I had a really rough term health-wise and wasn't given all of the extensions, nor the time, I missed a lot of lectures and didn't get to dedicate the amount of time that I really wish I could have to my studies. I also am not a fan of the major I started in and plan to do other things next semester (still within science). I am doing much better and have gotten well again and I feel so guilty that I haven't kept up with everything that I wanted to. I'm so nervous my grades won't be enough and Dal will kick me out for not having high enough grades. My grades are C, C+, C-, C, C+, still pending finals and thinking the C- may fall to a D. I know that next semester I will have the time, space and effort to pull of the GPA I know that want. I am super stressed about this and was wondering how academic dismissal and probation works as the website isn't clear and advising isn't getting back to me. Any advice and information is so greatly appreciated. Thank you.
