There are few early signs of pregnancy that a woman can experience very early in her pregnancy, even before missing her menstrual periods. Unluckily these signs are very much similar to the signs and symptoms a woman may experience before the start of her menstrual period.

This makes it difficult to distinguish between the two. The proper determination of the pregnancy before missing the period or before taking the pregnancy test is more like putting a piece of puzzle together. Some women do not experience any sign of pregnancy others may experience all. However there are bright chances that every pregnant women experience at least one early sign of pregnancy.

First sign of pregnancy is the change in size, shape and feeling of breasts. Some women experience tender breasts. In some other women the breast may not become tender but become slightly swollen. This may take place within first few hours of conception. The body of the woman starts to prepare itself for the development of the baby right from the first day.

Second early sign of pregnancy is the lack of energy. Some woman may feel completely tired and exhausted very early in her pregnancy. Sometimes they link this tiredness to other routines things. But if the tiredness is associated with pregnancy it is because of the hormonal burst and the strenuous work that body has to do soon after conception.

Third earliest pregnancy sign is implantation bleeding. This is not a common pregnancy sign but it does occur. Just after few days of conception the women may experience light brown or pinkish vaginal discharge. The discharge is the result of the implantation of the fertilized egg in the lining of the uterus. If a woman does not experience vaginal discharge that does not mean that she is not pregnant as implantation bleeding takes place in only 1/2 of the pregnant women.

Fourth but the trademark of pregnancy is nausea. Sometimes women may think that this nausea is because of the food poisoning or some viral attack. Nausea generally grows slowly so it is often considered stomach flu. However if the nausea do not subside, it is a sure indication that the woman may be pregnant. Some women also feel achy with nausea.

Fifth but sure sign of pregnancy is missed period. It is a sure indicator that a woman is pregnant. If a woman fails to tip off the fact that she is pregnant via nausea then missed period does this for her.

Sixth sign of pregnancy is an increased hunger. When the missed period and nausea are setting in, sometimes women also report an increased hunger. Probably this is because the body has to work hard to support the developing embryo.

Unfortunately there is no checklist that can determine the pregnancy.
