Vaginal itching in the third trimester: what to know

Vaginal itching in the third trimester should be assessed when persistent, intense, or accompanied by discharge, pain, rash or other pregnancy symptoms. Hormonal and moisture changes can irritate the vulva, while thrush and skin conditions are also possible. Treatment choices during pregnancy should be confirmed with your maternity clinician, doctor or pharmacist.

Thin, white discharge without a strong smell can occur in pregnancy, but thick or lumpy discharge with soreness may fit thrush. A fishy or unpleasant odour, yellow or green discharge, pelvic pain or burning urine needs assessment for infection. Red, cracked, pale or thickened vulval skin may point to a condition such as lichen sclerosus. Itching that is widespread, especially on the palms or soles, or worse at night, should be reported promptly because pregnancy-related liver problems can also cause itching without a local rash.

Wash the outer vulval area gently with water or an unperfumed cleanser, then pat dry. Choose loose, breathable underwear and change out of damp clothing. Avoid douching, scented liners, bubble bath and scratching, which can damage irritated skin. Contact your maternity team before using vaginal medicines, creams or oral treatments; they can recommend an option appropriate for your pregnancy and symptoms. Do not assume every itch is thrush.

Contact your maternity unit promptly for reduced fetal movement, vaginal bleeding, leaking fluid, regular painful contractions, fever, severe pelvic pain or feeling very unwell. Seek same-day advice for intense generalised itching, especially on the hands or feet, or itching with dark urine or yellowing skin. Arrange review for persistent local itching, sores, swelling, abnormal discharge or pain when passing urine.

Ask whether the symptoms need an examination or swab, whether liver tests are appropriate, and which treatment is safe at your stage of pregnancy. Mention any new products, medicines, discharge changes, sleep-disrupting itch, reduced movements or previous episodes.
