don't know what to think...

Well, right now I woke up to spotting.. I don't know what it means but yesterday I went to primary doctor because my OB couldnt see me fast enough. The doctor had told me although I don't have a UTI, my urine is showing protein and blood. She also said something else but I don't remember. She also said that she doesn't know exactly if it's miscarriage signs.? I've been having pelvic pain and back pain along with chills. Now I just don't know what to think..  If I am miscarriaging, I'm still going to be really upset. I'm trying to keep positive but it's hard at this point.
