I'm not sure if I have a UTI or what this is?

This morning I woke up and I was itchy, burning, and it burned to use the bathroom. I don't have an STD. It seems to be maybe irritated but idk what would have caused it? Is this a UTI? Or what do you think this could be? I've never had this problem before! Me and my husband actually haven't even had sex for while so I know it's not due to that. Also I have no odor. So I figured it wasn't a bacterial infection. I use to get bladder infections bad when I was small but I don't remember the symptoms I had, so maybe that's causing this? Please someone help!
