You have missed your period. Gradually, the symptoms are showing their face. You are pregnant; you think so. Well, now is the time to confirm your doubt. Take a pregnancy test.

There are two choices - go to your doctor and get a test done or buy a home pregnancy test kit and do it on your own.

The Mechanism Behind Pregnancy Test

Your egg, which has been fertilised by the sperm, is now sitting cozily in your uterus, means it has been implanted. Your uterus is now called womb. When this takes place, the placenta starts to develop and releases the hormone HCG into your blood. Some amount of HCG mixes wth your urine too. In the initial stages of pregnancy, that is the first 2-3 weeks, the amount of HCG increases rapidly. It doubles every second to third day! The pregnancy tests are nothing but detecting the presence of this hormone in your urine, henceforth, telling you whether it's time to celebrate or not.
