Small amount of blood

kim
Has anyone had a small amount of blood in their urine after ovulating? Like I couldn't even tell but I went to the doctor because I had been nauseous and cramping and that's when he told me. He said it's a small amount and I'm suppose to go back this Friday for another test. My AF is due Saturday. .. here's to hoping it's because I'm pregnant. This would be my 3rd month ttc.
