Typical early pregnancy signs and symptoms are directly associated with increasing hCG levels. Early pregnancy symptoms affect all major body systems producing a range of physical symptoms from pelvic pain, missed periods, nausea, vomiting, and heartburn to abdominal achiness, hemorrhoids, and shortness of breath. All are one way or the other related to increasing hCG levels. 

The mother-to-be can also expect her areolas to grow darker, a darkened line to appear from her navel to the pubic bone, discoloration of the face, and her feet to grow larger. Physical changes during pregnancy are commonly associated with hormonal changes. The body typically returns to normal a few months after the baby is born.
