UTI before frozen embryo transfer: what to know

Burning urine, urgency, frequent trips to the toilet, lower abdominal pressure, or blood in urine can signal a UTI, although vaginal or medication-related symptoms may feel similar. Your fertility team needs to know about symptoms, fever, and all medicines because the transfer cycle may include hormones and carefully timed appointments.

The team may request a urine test and decide whether treatment is needed. They may review whether symptoms have settled before proceeding, or adjust the schedule when illness or medication makes that safer. Frozen Embryo Transfer is planned around the uterine lining and embryo timing, so do not change progesterone or another cycle medicine without instructions.

Call the fertility clinic as soon as urinary symptoms appear, even if the transfer appointment is close. Provide the symptom start time, any temperature reading, allergies, previous urine infections, and a list of prescribed or over-the-counter medicines. Take prescribed treatment exactly as directed and complete the course unless the prescriber changes it.

Drink normally and avoid using someone else’s antibiotics. Ask whether to attend a scheduled urine test, continue planned medicines, or pause any medicine until the clinic responds. Micronised Progesterone may be part of a cycle plan, but the clinic should give you the exact instructions for your prescription.

Seek urgent care for fever or chills, pain in your side or back, vomiting, faintness, confusion, or rapidly worsening symptoms. Tell the fertility team promptly if you become unwell; a significant infection may need attention before any elective fertility procedure.

Ask whether you need urine testing, whether the transfer date should change, and which symptoms require urgent review. Confirm exactly how to take Micronised Progesterone and whether every medicine you use is compatible with your treatment plan.
