When taking a home pregnancy test, questions often arise about the results of the test, regardless of whether they are positive or negative.
One common question many women have is about the impact of birth control pills on the results of a pregnancy test. Can birth control pills cause false results? Can a woman get pregnant while taking birth control pills? The placenta begins to produce hCG shortly after the embryo implants in the pregnancy test and birth control, and the hormone reaches detectable levels for most women by the time her period is due.
To take the test, urine is placed on an absorbent pad with a dropper, by dipping the pad in collected urine, or by holding the pad in the urine stream. There will always be one line that develops on a pregnancy test regardless of whether or not the test is positive, pregnancy test and birth control.
In a positive test, a second line or a plus sign will appear in the allotted time for the test, pregnancy test and birth control. The allotted time varies between brands and your test should not be read before or after this time. These two hormones control ovulation, or the release of an egg from her ovaries. When ovulation does not occur, a woman cannot become pregnant. According to the National Institutes of Health, the design and chemical specificity of a pregnancy test makes it impossible for birth control hormones to cause a false positive.
According to Planned Parenthood, pregnancy test and birth control control pills are considered 99 percent effective when they are taken correctly. So, one out of every one hundred women who take birth control pills will get pregnant while taking them as prescribed. However, many women have trouble remembering to take them at the same time every day, or may take them with other medications that interfere with their effectiveness, such as antibiotics.
In these instances, pregnancy can occur. You may take a home pregnancy test any time you suspect that you may be pregnant. However, the chances for a false negative will be reduced if you wait until the day you would normally expect your period to start. Taking the test before this day can give you a positive if indeed you are pregnant, but you may get a false negative if you have not had enough time between conception and testing for the hCG to build up to detectable levels in your blood stream.
If you are taking birth control pills, your pill pack should tell you when to expect your period. However, some birth control pills limit the number of periods that you have during a year.
If you suspect that you may be pregnant while taking these types of pills, testing 12 to 14 days after you suspect conception should give you a reliable positive or negative result. Video of the Day.
