Going to test on Friday but just wondering if there might be another explanation?

I took a negative test a week before my period was due, it’s now a week late and I’ve been cramping, kinda nauseous, feeling pelvic pain and peeing a whole lot more that I used to. I’ve also been quite bloated. I wondered about a UTI because of the increase in having to pee but I have no burning nor do I feel like I need to pee but barely anything comes out.
