What should you know about embryo transfer failure?

Transfer is the procedure that places an embryo inside the uterus. A negative pregnancy test means implantation or ongoing development did not result in a detectable pregnancy in that cycle. It does not identify one certain cause. Factors may involve embryo development, the uterine lining, timing, sperm or egg factors, or chance. A failed cycle is emotionally difficult, but it does not by itself predict what will happen in a future cycle.

Follow the clinic's instructions about the pregnancy test and prescribed medicines. Do not stop hormonal support without checking with the fertility team. Arrange a review to discuss the embryo used, the lining preparation, transfer timing, and whether any change is sensible before another attempt. Your clinician may recommend waiting for bleeding, completing a planned test, or adjusting the next protocol. Read more about [IVF](/treatments/fertility-and-assisted-reproduction/ivf/) and [Micronised Progesterone](/materials/micronised-progesterone/).

Contact your clinic promptly for heavy bleeding, severe or worsening pelvic pain, faintness, fever, breathlessness, or marked abdominal swelling. Seek urgent medical help for collapse, intense one-sided pain, or trouble breathing. These symptoms need assessment regardless of the pregnancy result and should not be explained away as a failed transfer.

Ask which result was confirmed and when medicines should change. You can also ask what the embryo and uterine-lining details show, whether another test is appropriate, what would be changed in a future cycle, and when it is medically and emotionally reasonable to try again.
