What should you know about a double frozen embryo transfer?

In a frozen embryo transfer cycle, embryos created during an earlier fertility treatment are stored and later thawed for transfer. The womb lining may be prepared during a natural cycle or with prescribed hormones. The team checks the lining and times progesterone and transfer according to the chosen plan.

On transfer day, a clinician places a thin catheter through the cervix into the womb and releases the embryos. Two embryos may be transferred when the care team considers the clinical circumstances and treatment goals. This also raises the possibility of a multiple pregnancy, so ask how the number transferred affects monitoring and pregnancy care.

Take prescribed medicines exactly as directed and do not stop progesterone without speaking with the clinic. [Micronised Progesterone](/materials/micronised-progesterone/) may be used for luteal support in some plans. Attend scans and blood tests, and confirm the timing of the pregnancy test with your clinic. Ordinary gentle activity is often acceptable, but follow advice specific to your procedure and health.

The transfer itself is usually brief. Mild cramping or light spotting can occur afterward, while symptoms cannot reliably show whether implantation has occurred. For an overview of the procedure, see [Frozen Embryo Transfer](/treatments/fertility-and-assisted-reproduction/frozen-embryo-transfer/).

Contact the fertility clinic for heavy bleeding, worsening pelvic pain, fever, or concerns about medication. Seek urgent care for severe pain, fainting, breathing difficulty, or marked abdominal swelling. After a positive test, one-sided pain, shoulder-tip pain, or bleeding needs prompt assessment because pregnancy location and complications must be checked.

Ask why two embryos are recommended, what multiple pregnancy could mean for you, how the womb lining will be prepared, and when each medicine should be taken. Ask what happens if an embryo does not survive thawing and which symptoms require same-day advice.
