Hello so basically since about the 20th I had a UTI, called my doctor gave my symptoms and was prescribed a 3 day course of antibiotics which helped a little bit! Now I have quite bad back pain but only on a night for some reason, still have an unpleasant pressure feeling every time I finish peeing and have cloudy pee but all the other uti symptoms have subsided so I dropped a urine sample in docs on Friday just in case I could possibly have a kidney infection which I’m hoping to hear back about on Monday as I’m terrified from reading Google that it could cause sepsis and possibly kill me, I’m so bad at over thinking constantly googling and have bad anxiety that I will die from all kinds of illnesses 
so any kind of reassurance and other peoples outcomes from the same symptoms would be much appreciated and also any opinions as to why I’m 5 days late but had 2 negative tests! Sorry for the hugeeee paragraph!!
