Now that there are pregnancy tests that can tell if you are pregnant before a missed period, the question is “how long before I can take a pregnancy test?” How long before a pregnancy test is accurate is difficult to determine. The test won’t be positive until there is implantation, which is usually 9 days after ovulation or 5 days before a period. The problem is that implantation can take up to 11 days after ovulation or 3 days before a period. This means you can get a false negative test if you test before implantation has officially occurred and may not know you are pregnant until later in the pregnancy.
How Long to Wait Before Taking a Pregnancy Test?
Some women are just too anxious to take the pregnancy test and try to take it up to 2 weeks before a missed period. They don’t realize that this is the time of ovulation and it is much too early to take a pregnancy test. Even trying to take a pregnancy test 10 days before a period is too early. It takes at least 9-11 days after ovulation or 5-6 days before a missed period in order for the embryo to implant and begin to leach HCG into the maternal serum.
