The home tests have similar results to the pregnancy tests done on urine in most doctors' offices if they are used exactly as instructed.When the fertilized egg implants, the placenta starts to develop and begins to release h CG into the woman's blood. In the first few weeks of pregnancy, the amount of h CG in the urine gets higher very quickly-it doubles every 2 to 3 days. The first urine of the morning (that has collected in the bladder overnight) is the best one to use and has the most accurate test results.The accuracy of home pregnancy tests is different for every woman because: You can buy home pregnancy test kits at the drugstore or grocery store. The test kits generally have plastic dipsticks or test strips and instructions that explain how to do the test.
If the test does not show you are pregnant (negative test), it is still possible that you may actually be pregnant.
If you are using a midstream kit, urinate a small amount first and then hold the dipstick in your urine stream as you finish urinating.
Test the urine sample according to the directions included in the test kit package.
When a woman becomes pregnant, the egg is generally fertilized by a sperm cell in a fallopian tube (conception).
Within 9 days after fertilization , the egg moves down the fallopian tube into the uterus and attaches (implants) to the wall of the uterus.
