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?
Will Birth Control Pills Affect Pregnancy Test Results?
Man-made estrogen and progestin hormones in these birth control methods not only prevent the release of eggs from the ovaries, but also make the cervical lining inhospitable to sperm. When taken according to the directions, pregnancy tests work by detecting levels of the hormone called human chorionic gonadotropin hCG. This hormone is produced approximately six days after you conceive, and it will continue to rise as time goes on. The Mayo Clinic explains that while fertility medications may impact pregnancy test results with a false positive, oral contraceptives have no effect on hCG levels. The reasons for false negatives include taking a test too soon or not following the test instructions carefully.
Birth control pills are a popular and effective method of contraception. However, some factors, such as missing pill days, vomiting, and taking certain medications, can reduce the effectiveness of the pill and may result in unintended pregnancies. In this article, we look at how effective the birth control pill is, and five reasons why the pill might fail.
To stimulate the ability of the uterus to respond to increased estrogen, the woman should be given a higher-dose pill or Premarin 1. If the uterus does respond and there is a withdrawal flow, uterine pathology should be ruled out. Withdrawal flow should be stimulated with increased estrogen after 3 months of amenorrhea while taking the pill, provided pregnancy tests are negative.
