The last day of my period was the 20th of November. I have not had any symptoms of pregnancy but I think that I may be pregnant. I should have already had or started my period by now but I am still waiting. I would be around 3 weeks pregnant but I am not sure if it is to early to take a pregnancy test.
Learn more about this top honor. The fecal occult blood test (FOBT) is a lab test used to check stool samples for hidden (occult) blood. Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum â though not all cancers or polyps bleed. Typically, occult blood is passed in such small amounts that it can be detected only through the chemicals used in a fecal occult blood test.
Occult blood is a laboratory test to see if there is blood hidden in the stool. Testing for occult blood is usually part of every routine physical examination. It may also be done if you are having abdominal (belly) pain. Blood in the stool may be an early sign of a serious problem. Since colorectal (co-lo-REC-tull) cancer is the second leading cause of cancer deaths, early detection is essential. Some foods and dyes, beets and food colors for example, change the color of stool so that it may look like it is bloody.
