If you are spotting (through the vagina) after a heavy bleeding, then pregnancy
should be suspected. You might going through a spontaneous abortion
and so a pregnancy test should be done right away first. Urine test should also be done to actually confirm the UTI ( which might be the cause of the spontaneous miscarriage
). If there is no pregnancy, then you need to see a gynobs to determine the cause of your abnormal vaginal bleeding
. There are a wide range of causes that will need to be excluded one after another. If urinary tract
then a course of antibiotics should have been started. Your bleeding is not a UTI but if pregnant then could be the course of your bleeding as a pregnancy complication.
First step is to do a pregnancy test. Next step is see a gynobs urgently irrespective of pregnancy test results. Continuous bleeding can lead to blood shortage/anemia which can seriously complicate your health.
Hope this helps
