The short explanation
Thrush is more common in pregnancy because hormone changes alter the vaginal environment, and it is not usually harmful to the baby. It causes itching, soreness and a thick white discharge that can look like cottage cheese. It is uncomfortable, but it is treatable. The important point in pregnancy is to get it checked rather than self-treat. Some treatments used outside pregnancy are not suitable while pregnant, and other infections that matter more in pregnancy can look similar. Your antenatal doctor can confirm what it is and choose a treatment that suits pregnancy.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Thrush can come back several times during pregnancy and often settles after the birth. Recurrent episodes are worth mentioning, because the doctor may check your blood sugar, as gestational diabetes can make thrush more likely.
- Pain when passing urine, fever, a bad smell, green or grey discharge, or any bleeding suggests something other than simple thrush.
- Loose cotton underwear and avoiding perfumed products help with comfort.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot confirm that your discharge is thrush. Only an examination, and sometimes a swab, can do that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this thrush, or could it be another infection?
- Which treatments are suitable for me in pregnancy?
- Should my sugar be checked because the thrush keeps returning?
- What should make me come back before my next antenatal visit?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have heavy bleeding, severe abdominal pain, or a sudden gush of fluid with fever.
Get help the same day
- Get care the same day if you have any bleeding, a watery leak you are unsure about, fever, or burning with urine.
Book an appointment soon
- See your antenatal doctor within a few days about itching and curd-like discharge, even if it seems mild.
Raise it at a routine appointment
- Mention any recurring thrush at your routine antenatal visit.
