Is embryo transfer done with micronised progesterone?

Progesterone helps prepare and maintain the lining of the uterus during the part of a cycle when an embryo may attach. Micronised progesterone is a form of the hormone used in fertility care. Depending on the cycle, it may be given through the vagina or by another route chosen by the clinic. The timing begins before or around transfer and may continue while the team checks the result of treatment.

Follow the prescribed dose, route and schedule, and do not stop it without speaking with the fertility team. Mild discharge or local irritation can occur with vaginal use. Record missed doses and ask the clinic what to do rather than doubling the next dose. Tell the team about all medicines, allergies and any previous reaction to progesterone.

Seek urgent medical help for chest pain, sudden breathlessness, coughing blood, one-sided leg swelling, severe headache with vision changes, or fainting. Contact your fertility clinic about heavy bleeding, significant abdominal pain, or a reaction that worries you. These symptoms need assessment and should not be explained away as a normal effect of treatment.

Which route and dose should I use? When should I start and stop? What should I do after a missed dose, bleeding, or vomiting? Which symptoms mean I should contact the clinic immediately?
