Hello I'm A 30 Year Old Female. I Went To

Hello i'm a 30 year old female. I went to a walk in clinic recently for some on and off again pain on my right side. they ran a urine test and told me my protein level was at 30mg and I had a small amount of blood in my urine. They said they were going to send the urine away for more testing. I just received a call that is there is no infection. Are there other things I should worry about other than infection? Should I follow up on this or just let it go?
