Most doctors recommend that you wait until the first day of your missed period before taking a urine pregnancy test. This is usually about two weeks after conception. However, some tests are more sensitive than others and can be taken earlier.
You want to take a pregnancy test, but you have questions: How long do I have to wait after a missed period before I take a test? How long after implantation can I test? It can be confusing. A positive pregnancy blood test first happens about 3-4 days after implantation bleeding and about 4-5 days before a missed period.
