I'm scared. It's burns when I pee.

So I stared my period Wednesday of last week. Before my period nothing was wrong with my 😻, no burning sensation, no problem. But it's recently started (Monday- Wednesday of this week) burning when I pee, once when I sat down. I'm scared that I have an infection. If anyone can relate or has (had) the same issues please tell me what might be going on so I can treat it before it gets worse. Thank you babes💓
