Bleeding on urine

Hello ladies! Im due on Feb. 24, and its been a long week! I have some blood in my urine, I went to the hospital and they told me that it looks like a UTI that everything is fine with the baby. He is moving fine but I cant help to freak out! It is my third pregnancy and I had never experienced something like this, has anything like it happen to anyone? Im freaking out. Its a holiday weekend so the doctor is closed, I do not know if to go back to the hospital or what to do
