Ofcourse there is obvious pregnancy test but when should you take that test or when to decide that its time to go to doctor ? well here are some symptoms on which you an decide to take pregnancy test-

1) Cramp or a minor bleed

A tiny amount of bleeding or even spotting is observed in the stages prior to the pregnancy. This period is say at about ten to fourteen days after the fertilization. This bleeding is also well known as the implantation bleeding. Implantation bleeding occurs when the fertilized egg attaches itself to the inner lining of uterus. This kind of bleeding is observed in the early stages. The bleeding is light in color than that of the regular periods. The bleeding does not last for a long period. Also, the bleeding is spottier.

Pregnant women are also prone to experience a feeling of cramp at an early stage in pregnancy. During this time the uterus enlarges. Cramps similar to those of the menstrual ones are experienced.

2) Queasiness without or with vomiting

Morning sickness is one of the telltale signs of early pregnancy. Most women feel some sickness around four to eight weeks of pregnancy, but the queasiness can begin as early as two weeks after conception. The very telltale sign of pregnancy is the sickness experienced in the mornings. In the first 4 to 8 weeks of the pregnancy some kind of weakness is observed. The nausea can start in the early two weeks of pregnancy. This is immediately after the conception itself.

Vomiting and Nausea which is called as the morning sickness can occur in the other parts of the day as well. This brings a feeling of the stomach to be empty. The basis for the vomiting and the nausea is the rapid increase in the estrogen levels, which are manufactured by the fetus and the placenta. Such abnormal levels in the flow of the estrogen levels contribute to the emptiness of the stomach very slowly. This could be the reason for the cause of the vomiting and nausea. There also exists an increase in the sensation of smell. This can include a variety of odors such as the cooking foods, cigarette smoke or perfume itself. Such sensations also can trigger vomiting and nausea.

The two main major factors leading to the conclusive signs of pregnancy have been discussed.
