pregnancy symptoms week by week

Most pregnancies are often accompanied by changes in the functioning of a woman's body. These physical 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. Many of these pregnancy symptoms exist to such a degree that they are both unpleasant and have potentially negative effects on a woman's life.

Early Pregnancy Symptoms

Early pregnancy symptoms can sometimes happen before a missed period and before a positive pregnancy test. Early pregnancy symptoms and signs are usually related to the pregnancy hormone hCG or "Human Chorionic Gonadotropin" which is responsible for the typical pregnancy signs.
