Burning sensation

Hi, so I got my periods four days ago and my vagina started to burn a little bit. It wasn’t too painful but it was definitely annoying to feel that way. It also felt borderline UTI-like because I felt like peeing all the time for a day.

On the last day of my period the burning sensation got worse for like 5 minutes, to a point where I couldn’t stand. I took off my sanitary pad and the sensation was gone. I checked my pad and it was nearing its expiration date.

Have I developed an infection down there? And could it be because of the pads?
