Hi Customer (name blocked for privacy)-
The blood is not likely from the birth control pills. Your wife needs to go back to her doctor ASAP to have further tests done. She needs to have an endoscopy conducted to rule out upper GI tract bleeding (the colonscopy only examines the lower intestine). Her doctor may order additional tests as well, or refer her to a specalist.
It's very important that she learns where the bleeding is coming from. If her doctor is unable to find a cause, have your wife ask to be referred to a specalist. There could be a number of explinations for the bleeding, including:
* Hemorrhoids (which likely would have been discovered during the colonscopy, but the doctor should double check),
* Ulcers,
* Diverticulitis,
* Intestional infections, and
* Irritable Bowl Disease.

If you have any questions, feel free to ask!
Sincerely,
Emily
