New period symptoms?


So I got tested for a UTI and it came back negative. Im currently on my period and have experienced new symptoms. Lower back pain (that lasts more than a day), peeing more than usual, rumbling stomach (not bloated or hungry), pain in left and right side of stomach next to belly button, and pelvic pain/pressure. I’m 23 years old. I have 2 days left in my period. Has anyone ever experienced this?
