It is relatively easy to identify a pregnancy in the later stages, but early pregnancy signs may not be as obvious. Pregnancy tests are fairly reliable these days, but they are not right 100% of the time. Women who are wondering if they might be pregnant can watch for some early signs that, when noted together, could indicate pregnancy.
Most people know a late period could indicate pregnancy, but various environmental, mental, and physical factors can also cause changes or fluctuations in the menstrual cycle. This potential sign only becomes more solidly linked to pregnancy when a period is three weeks or more overdue. However, it is possible to miss an entire period for reasons other than pregnancy.
