If you do not use a very sensitive pregnancy strip, it’s likely you will get a false negative result. Generally, it takes some days for pregnancy to be detected in a urine strip and accuracy is less than a blood test. In most women, a blood pregnancy test will detect pregnancy 3 – 4 days before period.
If you expect your period on Wednesday, Thursday would be the day of your missed period. Likewise, first morning urine may be more concentrated and detect hCG more accurately. "Early results" pregnancy tests promise results as soon as three to six days before your missed period. These tests are more sensitive than standard tests, but getting accurate results that early is more difficult simply because ovulation and implantation times can vary. If you have irregular periods, it can be even more difficult to know when might be an accurate time to try an early test. After a fertilized egg implants into the uterine wall, a woman’s body starts producing a pregnancy hormone called human chorionic gonadotropin .
When Do Pregnancy Symptoms Start?
The earliest you should test is one day after you expected your period to start. Keep in mind that the earlier you test, the more likely you are to get a false negative, even if you are pregnant. If you're not alreadykeeping a fertility calendar, proper pregnancy test timing is a good reason to start one. According to the Food and Drug Administration , the accuracy of pregnancy tests relies heavily on how a person follows directions and interprets the results. The FDA also notes that while these tests are able to detect hCG, if someone tests too early there may not be enough hCG for the test to detect.
If the embryo is day 3, day 4 or day 5 embryo, it can produce a different amount of ECG. But normally, at our unit, we would recommend doing a urinary test as usual two weeks after the embryo transfer. For more than 95% of the patients here, we test for pregnancy on the fifth day of the transfer.

IVF is successful when you have a healthy, viable pregnancy after the embryo transfer. You did not read the instructions on your strips before testing. This is because it takes at least 1 – 2 weeks for fertilization, implantation, and rise of HCG hormone to occur.

For example, your doctor may order two beta hCG tests a few days apart to see whether the level of hCG is increasing as expected or not. This might be important if you had trouble conceiving, have a history of early miscarriage, or an ectopic pregnancy is suspected. The time of day you take a pregnancy test does matter to a certain extent. You’re more likely to get an accurate result if you take the test in the morning.

A clinical pregnancy is when the embryo implants in the uterus and is identified by ultrasound at 5-6 weeks of gestation. If you have a negative pregnancy test at least 9-10 days after a blast transfer, the transfer was unsuccessful. An early negative urine pregnancy test doesn’t mean that the transfer has failed. You should generally wait at least 9-10 days after a day 5 blast transfer and after a day 3 transfer to check the test. It is detectable only when there is evidence of embryo implantation. The amount of beta HCG produced by the placenta increases at this rate with the period of gestation in a viable fetus.
All pregnancy tests measure the amount of human chorionic gonadotrophin , the pregnancy hormone, in your body. Home pregnancy tests detect the presence of hCG in your urine. There is a specific duration of time to wait before reading the result. Or at least she should not have voided urine for 4 hours duration. Don’t drink too much fluids to increase the amount of urine, because it may dilute the concentration of HCG present in urine.

Likewise, if you routinely had unprotected sex with your boyfriend, and tested negative to pregnancy days after, It still does not exclude pregnancy. If you are trying to conceive, pregnancy test immediately after an unprotected sexual intercourse will get you disappointed. This is usually days after embryo transfer, and may depend on the stage at which your embryos were replaced.
Knowing when to take a pregnancy test if you have an irregular period can be downright confusing. Pregnancy tests on the market today all boast take 3 days before your missed period for best results. As for timing, implantation usually happens between days 6 and 10 days after fertilization. Symptoms you may experience are mild and include things like cramping and light spotting.
From implantation to adequate levels of hCG
Many clinics will schedule you for a pregnancy blood test at the 14-day mark. A blood test can detect lower levels of hCG and is considered even more accurate than urine tests. But these symptoms don’t always occur, even in women who are pregnant. The only sure signs are a missed period with a positive pregnancy test from your doctor’s office. Sure, if the fertilized egg only takes 6 days in your case, you may be able to take a pregnancy test at 9 or 10 days post-IUI and get a faint positive. But you could also get a negative when, in fact, everything worked — and that can be discouraging.
