Thank you for the information. Based on your description, it seems like blood spots are there more often and it was not an occasional things. Itching in genital region is commonly associated with yeast infection/vaginitis, but you don't seem to have any other supporting yeast symptoms at this time. The amount of bleeding appears very small, it could be due to local causes such as rawness, friction, infection, urethra related problems etc. However, its relation with urination does suggest the need for investigation to rule out causes of bleeding/hematuria from urinary tract. Sometimes, bleeding is directly visible to eyes, but not always, so exploring the cause would be most appropriate action.
Just for your information, some of the common causes of bleeding related to urination are: Urinary tract infections, stone, Kidney disease, Cancer, Medications (Common drugs that can cause visible urinary blood include aspirin, penicillin, the blood thinners warfarin and heparin), Strenuous exercise. Most commonly, the causes are simple and minor like infection but still the exact cause of hematuria needs to be ruled out. I would suggest you to visit your doctor and have it investigated.
