Often times, it is hard to a woman to clearly determine whether they are leaking amniotic fluid or not. During the last trimester, the baby can put a lot of pressure on the body and this can cause discharge from the cervix which is normal. Also, the baby places pressure on the bladder and thus can cause leaking urine.
For instance, if a scientific study is performed, the primary source is the initial report that is prepared by the scientist(s) who performed the research. Secondary Source: A secondary source is a document that is written about the primary source
The authors of secondary sources develop their interpretations and narratives of events based on primary sources, that is, documents and other evidence created by participants or eyewitnesses. Frequently, they also take advantage of the work of other historians by using other secondary sources. For example, the author of the history textbook which you use in school probably did not use too many primary sources. Instead, textbook authors usually rely on secondary sources written by other historians.
