This is because the amount of hCG in your urine increases with time. HCG levels should almost double every 48 hours at the beginning of pregnancy, so if you are pregnant and you wait a few days to take the test, it is more likely to be positive.
The best time to take a pregnancy test is after your period is late. If you are pregnant, your body needs time to develop detectable levels of hCG. For example, if your cycles range from 30 to 35 days, the best time to take a test would be day 36 or later.
Something else to consider is whether you know if your period is even late. This is especially true if your period is not yet late, or if your period is only a couple of days late. Your urine is usually more concentrated when you first wake up. However, you can still take a pregnancy test at a different time of day. These tests assume a day luteal phase , which is the time between ovulation and when you get your period.
The problem is that you may have a shorter or longer luteal phase. If your luteal phase is usually 12 days, four days before your missed period would be nine days after ovulation. For you, taking the test four days before your missed period would be pointless. If you have a luteal phase of 15 days, four days before your missed period is 12 days after ovulation. You still may not have enough hormones that early. However, you have a better chance than someone with a shorter luteal phase. An early test may detect the remains of fertility medication.
Since the amount of hCG increases rapidly when you are pregnant, you may need to retest in a few days. If you are tempted to take a test before your period is late, consider the pros and cons before you do. Although, in theory, you could start taking pregnancy tests 10 days after conception, taking the test early may give you a negative result, even if you are pregnant.
As pregnancy hormones increase rapidly, the longer you wait, the more chance of an accurate result. The best time to take a pregnancy test is the day after your expected period, in the morning hours, with your first urination of the day. In the event of a positive result, contact your healthcare provider as soon as possible to discuss your options and potential next steps.
How does this happen? What could cause a pregnancy test to return a negative result when you are actually pregnant? One reason a pregnancy test may return a false negative result is that the test is simply taken too early in the pregnancy to properly detect the presence of a developing fetus. The sooner after a missed period a home pregnancy test is taken, the harder it is for the test to detect the pregnancy hormone human chorionic gonadotrophin, or hCG.
Every test is different, and some are more sensitive than others. A pregnancy test can usually detect hCG levels within 10 days of a missed period. To avoid a false negative or positive result and the roller coaster of emotions that could follow, wait to test until a couple of days after your missed period or, even better, until a full week has passed. By then, the chances of getting a false negative result are very low. If you get a negative result, keep in mind that you could still possibly be pregnant.
You might want to retest one week after your missed period to be sure. As such, wait about 14 days after you had sex to take a test. If you take two pregnancy tests and both are negative but you still believe you may be pregnant, contact your healthcare professional. The wait to take a pregnancy test can be excruciating.
But some good news is that the moment you hit the right time in your cycle, you can take it the first thing that morning. You want to take a pregnancy test just after you wake up and when you haven't used the restroom in a while. This is when your urine is the most concentrated, with the highest hCG levels.
The wait to take a pregnancy test can make for some of the most anxiety-inducing hours and days. But to make the most of it, waiting a little longer may make sense. Have a trusted family member, friend, or healthcare professional nearby. If you have any questions about your results or discover you are indeed pregnant, reach out to a doctor as soon as possible to determine which next steps are right for you.
