Vaginal secretions in pregnancy

Pregnancy hormones increase your normal, mucous secretions, so you will notice an increase in vaginal discharge when you are pregnant. 

This discharge should be clear or white, and it should not have an unpleasant smell. Any odour or discoloration should be investigated for infection. 

Thrush

Thrush is the most common vaginal infection. Thrush is a fungal infection that can affect the mouth, vagina or nipples and it is more common in pregnancy because of the changed acidity of the vagina. Even if you aren’t suffering any irritation, get it treated to avoid your baby being infected at birth.

Your doctor, midwife or pharmacist can advise you on treatments for thrush that are safe during pregnancy.

Discharge later in pregnancy

Particularly towards the end of pregnancy, some women experience wetness and are unsure what’s causing it. It could be increased vaginal secretions, or even a show in the run-up to labour. 

This wetness could also be urine - the weight of your baby and the relaxation of tissues can cause you to leak when coughing or laughing. Going to the toilet and emptying your bladder frequently can help or you might want to wear a pad to avoid embarrassment. Starting your pelvic floor exercises as early as possible, and continuing them for life, will help to avoid long-term problems. 

Another cause of wetness could be the ‘waters breaking’ - amniotic fluid following rupture of the membranes surrounding the baby. If you are unsure whether it could be the start of labour then speak to your midwife.
