UTI... worried!

Amber
Had my first doctor's appointment Friday and they suspect I have a UTI. They sent all the blood work and urine analysis off. I can see my results online and had 5 different tests come back abnormal and they indicate a UTI. Since it is a holiday weekend they are not open until Tuesday and I am worried! The OB nurse told me UTIs can cause miscarriage and I am terrified having had 2 prior miscarriage :( Anyone have good stories about UTI and healthy babies??
