Blood?

Im 22 weeks. I've been having cramps, kind of sharp menstrual cramp feeling, since last night. When I went to the restroom there was blood in my urine and when I wiped. My doctor said the vaginal bleeding was outside of my cervix and it's gone away. She is testing my urine to decide if she wants me to see a urologist, she is concerned it's not as simple as a uti or something because there is no pain. Any mommas had this?
