Two frozen embryo transfer: what to know

In a frozen embryo transfer cycle, the uterine lining is prepared either around your natural ovulation or with prescribed hormones. The clinic checks the lining and timing, thaws the selected embryos, and places them through the cervix using a thin catheter. If two embryos are transferred, both may implant, one may implant, or neither may implant. The number to transfer is discussed with the fertility team because a multiple pregnancy can carry additional risks for the pregnant person and babies. Micronised progesterone may be used when prescribed to support the uterine lining.

Take medicines exactly as directed and do not stop progesterone without speaking with the clinic. Follow the clinic's instructions about appointments, activity, and the pregnancy test date. Mild cramping or light spotting can occur, but these symptoms cannot confirm whether implantation has happened. Continue ordinary gentle activity unless your team advises otherwise, and ask before taking any new medicine. Keep the clinic's emergency contact details available during the waiting period.

Contact the fertility clinic urgently for heavy bleeding, severe or worsening pelvic pain, faintness, breathing difficulty, marked abdominal swelling, or fever. After a positive test, one-sided pain, shoulder-tip pain, or dizziness needs prompt assessment because an ectopic pregnancy and other complications must be considered. Do not interpret a negative or positive home test without following the clinic's testing plan.

Ask why two embryos are being considered, what multiple pregnancy could mean for you, how embryo quality affects the plan, which medicines to continue, and when the clinic will review the result.
