I think Im pregnant but went to the toilet and had a little bit of blood does this mean not pregnant?

Not necessarily. Bleeding during pregnancy is relatively common, and many women experience similar symptoms during early pregnancy. While bleeding can sometimes be a sign that you are not pregnant, especially when accompanied by other symptoms such as cramping and intense abdominal pain, the only way to know for sure is to take a pregnancy test. If you are concerned, it is best to visit a doctor or healthcare professional for further examination.
