Though pregnancy symptoms are different for each woman and each pregnancy, common early symptoms to watch for are headaches, tender breasts, nausea and lower backaches. Understanding the signs and symptoms of pregnancy is important because each symptom may be related to something other than pregnancy, according to American Pregnancy Association.
Blood spotting and cramping are common from six to 12 days after the egg is fertilized and implants in the uterus. The presence of a white, milky vaginal discharge occurs at about the same time. A woman's hormone levels rapidly change after conception. Because of the changes, her breasts become swollen, sore or tingly a week or two later. They also feel heavier, fuller or tender to the touch. The area around the nipples, called the areola, darkens. Fatigue, or feeling very tired, is normal in pregnancy and starts in the early stages of pregnancy, according to WebMD.
