According to the Canadian Cancer Society, normal post-Pap smear bleeding occurs for one to two days. However, if the post-Pap smear bleeding is heavy or persists, a patient should see a doctor, Cancer.net recommends.

Medicine.net advises that Pap smears that are stained with blood be tested in a pathology lab. Testing of samples with blood helps reveal if there was too much bleeding, which might make it difficult to give a definitive diagnosis based on Pap test results. It takes two to eight weeks for the lab results to come up, according to the Canadian Cancer Society.

If a pathologist's report implies too much bleeding, a doctor may recommend that a patient reschedule a Pap test, as Medicine.net states. However, many practitioners do not direct another Pap smear if a patient is in later days of menstruation, when bleeding is least expected. Thus, it is the amount and not a mere presence of blood in a Pap test that can raise a medical concern.
