Home pregnancy tests have become more popular as they become much easier to use and more accurate; amongst the questions most women have about them is which is the most sensitive pregnancy test? It is important to them to have the results as early as possible, and for those results to be accurate.

A pregnancy test works because it could detect a particular hormone, human chorionic gonadotropin or HCG, in the urine which occurs only during pregnancy. This hormone is produced by the body when a fertilized egg becomes implanted in the uterus and starts to grow. The HCG continues to multiply through each day of a pregnancy.

An at home pregnancy test checks the urine for hcg; in the doctor's office, the test is usually done on the blood and is followed by a pelvic exam for a much firm diagnosis. Home pregnancy tests are being used at home because women prefer to test in private, and they are very easy to use and more inexpensive as compared to a doctor's visit. While a blood test for pregnancy could tell if you are pregnant within six to eight days after ovulation, a home pregnancy test is normally only accurate after your first missed period.

Most women are not familiar with hcg levels. The hcg levels in early pregnancy can vary greatly. A level below 1,200 mlU/ml would ordinarily double every 48 to 72 hours, increasing sixty percent every two days. It continues to increase until the pregnancy has developed to about ten to twelve weeks. At that point it will either stabilize or perhaps drop slightly. An hcg level below 5 mlU/ml indicates no pregnancy, whilst one above 25mlU/ml is indicates pregnancy. If the level falls between the two, the test should be repeated together with a follow up test.

The most sensitive pregnancy test over the counter is actually the First Response Early Result Pregnancy Test, according to current data. It is capable of identifying pregnancy five days before a woman's first missed menstrual period. It is capable of detecting hcg in the urine at lower levels as compared to all other brands. The first response pregnancy test results are easy to read - if two pink lines show in the oval results window, the results of the test are positive and you will know that you are pregnant.

For the most sensitive pregnancy test brands, earlypregnancytests.com offers two varieties of early detection pregnancy test, which are over 99% accurate.

Once you have taken the pregnancy test, you will need to know what symptoms of pregnancy to expect. Everyone has of course heard of morning sickness and increased urination, but an expectant mother wants to know the pregnancy symptoms week by week so she knows what to look for and expect.

Up until week four of your pregnancy, there are no outward signs of the pregnancy, though the changes in your hormones may cause mood swings. This is the week you would ordinarily have your menstrual period, and you may take a pregnancy test and discover that you are pregnant. Around the fifth week, you may begin to experience morning sickness, frequent urination as well as tender breasts. Week six could find you with more pronounced morning sickness, along with a slight weight gain. By week eight, you may feel some bloating or heartburn, and your clothes may begin to be too tight.

Week ten usually means that you will have to begin to purchase larger clothes, but most of the earlier symptoms are beginning to subside. Week eleven and twelve are when the baby's heartbeat is normally noted.
