New associate banker, called out for the first time on my 5th week. Will I be okay?

So I have been associate banker now for 5 weeks and I tried driving to work but I felt so sick so I turned around and let my manager know I don’t think I can come in.

I know I’m still on my probation period so is this a big deal I know I shouldn’t just call out willy nilly I just felt horrible today. Any advice is appreciated.
