Answer from: Raúl Olivares, MD
We recommend testing for a positive pregnancy test 12 days after the embryo transfer. In some cases, it can be done even a couple of days before, especially if you’re doing a blood test. If you are doing a urine pregnancy test, if you do it only 10 days after the embryo transfer, the risk of having a false negative is going to be high. Sometimes, patients tend to do a pregnancy test 5-6 days after the embryo transfer, and they claim that the test was positive, and then on the due date for a real pregnancy test, the result is negative. In IVF cases, it can be caused because you have used an hCG drug-like Ovitrelle or any other drug to trigger the ovulation, and the hCG lasts for a few days in the bloodstream. The test is positive because the patient may still have some hormone levels, which have been used to trigger ovulation, not because they are pregnant.
I wouldn’t recommend carrying out the test in the next week of the embryo transfer. 10-12 days, so somewhere in between should be fine. If the urine test is negative, you still need to confirm it via a blood test. The urine tests are designed to become positive for 5-6 days after the lack of the period in a normal cycle, and here we are almost always doing the pregnancy test on the 1st day in which it could be positive. That’s why sometimes, the levels of hCG in urine may not be too high, and you may get a false negative, but it will be positive if you do the blood test.
When is the best time to test for early pregnancy after the embryo transfer?
Most likely, you’ve been trying to get pregnant for years, and you’ve gone through at least a few IVF cycles before. Before getting that positive result, you might be feeling excited but also very anxious. So, how early can I test for pregnancy after an IVF transfer? When is it most reliable?
