Help?!

I’m currently really confused about what’s happening to me right now.

So, long story short, I got a UTI 3 weeks ago, drank a lot of water, and I thought it went away. At first I thought that I was pregnant because of the symptoms but now I’m on my period. Currently I’m experiencing fatigue, frequent and URGENT urination, lower back pain, mild to moderate fevers, chills, nausea, and smelly poop (smells like coffee grounds)

I have talked with my aunt who’s a pediatric nurse and she told me that I would have to get blood work done to see if I have a bladder infection, but I also know that my mom has thyroid issues so I’ve been kind of curious if any of my symptoms relate to that?

Please, ANYTHING HELPS at this point.. I just want to get a better understanding of what could possibly be happening to me before I start freaking out 😭😰
