Natural frozen embryo transfer

The clinic tracks follicle development, the womb lining, and signs of ovulation using appointments, ultrasound, and sometimes hormone tests. Transfer timing is matched to the embryo's developmental stage and the timing of ovulation. This approach differs from a medicated cycle, where hormones are used to prepare the lining and schedule the transfer.

Ovulation may not occur predictably in every cycle, so the clinic may recommend postponing transfer if the lining or hormone pattern is unsuitable. Some people are prescribed Micronised Progesterone after ovulation, depending on the clinic's assessment and protocol.

Follow the clinic's instructions for scans, blood tests, ovulation testing, medicines, and the transfer appointment. Tell the team about new medicines, illness, bleeding, or a change in cycle timing. Keep activity and medication plans clear after transfer; ordinary gentle movement is usually compatible with care, but follow your clinic's specific advice. Do not stop prescribed treatment without speaking with the fertility team.

Ask how and when pregnancy testing should be done, because testing too early can be confusing. Make sure you know who to contact outside clinic hours and what symptoms they want reported.

Contact the fertility clinic for heavy bleeding, increasing pelvic pain, fever, foul-smelling discharge, or concerns about a missed medicine. Seek emergency help for severe one-sided pain, fainting, shoulder-tip pain, or heavy bleeding, especially after a positive pregnancy test. These symptoms need assessment and should not be explained away as normal treatment effects.

Ask: How will you confirm ovulation? What happens if ovulation is late or does not occur? Will I need progesterone support? When is transfer scheduled? Which medicines should I continue? When should I test for pregnancy, and which symptoms require urgent help?
