How long after a missed period can i take a pregnancy test?

Immediately: If you have regular monthly cycles, a pregnancy test will be positive by the time your period is due. A pregnancy test is positive as early as ten days after conception - and conception occurs within 24 hours of ovulation. Since you ovulate about 14 days before your period, a pregnancy test could be positive about 4 days before your period is due.

HPT: You can do it the same day you miss your period. Some women wait a weak. There are early response type tests that can be used prior to missing a period.

1 week late: Home pregnancy tests generally become positive when you're about 1 week late with respect to your period. If it's negative, repeat in 1 week.

Anytime: However, if you want it to be accurate the test must find chemicals in your pee created by the pregnancy. These are detectable in increasing amounts around 2 weeks after exposure or about the time a menses is expected. OTC urine pregnancy tests are more likely to be falsely negative taken early. If positive the test is likely accurate.
