Although some women may not experience any symptoms the first week of pregnancy, others can experience spotting or cramping. These symptoms can develop between a week to 12 days and are due to bleeding implantation after egg fertilization, explains WebMD. Some other early symptoms can be absence of a period, breast tenderness and fatigue, according to the American Pregnancy Association.

For most women, an early sign of pregnancy is not getting their period. Another telltale sign is changes in the breast, which can include soreness and tenderness. These symptoms can manifest 1 to 2 weeks after conception, reports the American Pregnancy Association. A usual change in breasts can be a change in color around the nipple area.

Another early sign of pregnancy, which some women may experience in the first week, is feeling tired. Many of the other signs of pregnancy, such as nausea, morning sickness, backache and weight gain, tend to occur approximately 2 to 8 weeks after a woman conceives.

Although these many all be signs of pregnancy, some of these symptoms can be associated with other medical problems, stresses the American Pregnancy Association. For example, fatigue may be caused by a hormonal imbalance, and a missed period can be due to stress. By taking a pregnancy test, a woman can know for sure if she is pregnant.
