Some women, using early pregnancy signs alone, can typically tell that they are pregnant long before they have taken a pregnancy test. For women who have had children in the past, these tell-tale signs are generally quite easy to identify. However, for those who have never been pregnant, many of the more common symptoms can easily be mistaken for a flu or a cold. By understanding the changes that a one’s body goes through when she becomes pregnant, a woman may be able to determine whether to seek out a pregnancy test administered by a medical professional much earlier on in her pregnancy.
