For most home pregnancy tests, you put the end of the test in your urine stream, dip the test in a container of urine or put several drops of urine onto the test. It's often a plus or a minus sign, the words "yes" or "no," one line or two lines, or the words "pregnant" or "not pregnant." In one European study, seven pregnancy tests were tested for accuracy. Three of those seven tests were accurate 97.6% to 100% of the time.
Irregular period, worried about pregnancy
Human error or defects can also result in unplanned pregnancy. Birth control pills can be difficult to remember to take each day. According to Planned Parenthood, 9 out of every 100 women on the pill will get pregnant if they don’t take it as directed. As your pregnancy produces more and more estrogen and progesterone, these hormones start to make changes in your body to support the baby’s growth. Results may show up as a line, a color, or a symbol such as a "+" or "-" sign. Digital tests show the words "pregnant" or "not pregnant." It's important to know what a positive or negative result means.
Qualitative tests measure whether hCG is present in your blood or urine. This is especially true if your period is not yet late, or if your period is only a couple days late. Qualitative point-of-care and over-the-counter urine hCG devices differentially detect the hCG variants of early pregnancy. Ovaries release an ovum on around day 14 of the cycle. An unfertilized ovum can remain viable in the female genital tract for about 5 to 8 days.

How soon can you take a pregnancy test?
Pregnancy actually doesn’t start the day a couple has intercourse. It can take up to six days after sex for the sperm and egg to join and form a fertilized egg. It then takes another six days for the fertilized egg to implant itself into the lining of the uterus to start a pregnancy. Pregnancy tests check your pee or blood for a hormone called human chorionic gonadotropin . Your body makes this hormone after a fertilized egg attaches to the wall of your uterus. While home pregnancy tests are growing ever more sensitive and accurate, there is a limit to how soon a pregnancy test you buy can work.
Before you take the test, make sure you understand what the readout for “pregnant” and “not pregnant” will be. Some tests still use two lines to indicate you are pregnant and one to indicate that you aren’t. However, many tests have switched to words such as “yes” and “no”, or “pregnant” and “not pregnant” for additional clarity.
