Is irritation/a little itching normal during a uti? And I don't have much discharge at all.

Here are some… UTI-related irritation on voiding is usually continual. Sporadic mild irritation may occur to some people, but is not related with UTI, instead, with something what we eat. So, seek professional evaluation to review the detailed history of symptoms and their sequence of events + proper urinalysis + other tests as needed, which will help clarify such confusion. Best wish…
