Content: However, it’s best to wait at least a week after your missed period to be sure that you get the most accurate test results. Home pregnancy tests
A home pregnancy test (HPT) can be used on the first day of your missed period. Some very sensitive tests can be used even earlier. These tests work by detecting the hormone human chorionic gonadotropin (hCG) in your urine. This hormone is only found in the body during pregnancy. A chemical in the stick changes color when it comes into contact with this hormone. Waiting times will vary depending on the test, but most take about 10 minutes to deliver an accurate reading. Most manufacturers recommend that HPTs be taken twice, since results may vary if you take a test too soon after your first missed period. In some cases, your hCG levels are too low to catch early on. Applicators vary from brand to brand, but the tests are generally inexpensive.
