It is normal for your vaginal discharge to increase in pregnancy, due to a combination of increased vaginal cell growth and sloughing off, and increased mucous production to help protect your baby from infection by flushing out bacteria before it can move up into your cervix.
The discharge is usually quite thin and whitish and not smelly.
If you are getting thick, ‘cottage cheese’ discharge that is itchy and/or yeasty-smelling, you may have a candida (yeast) infection. Contact your midwife, who may ask you to do a swab and/or prescribe treatment for this.
If it is yellowish, greenish or greyish, or has an offensive smell, you may have an infection, and your midwife may want you to do a swab and prescribe the right treatment for you. Please call your midwife about any symptoms like this.
If your discharge is very watery, it may indicate an amniotic fluid leak, or it may be just normal pregnancy discharge. If you are concerned that it may be amniotic fluid, please call your midwife, especially if you are not yet 37 weeks pregnant.
If you are bleeding from your vagina, please call your midwife. Small amounts of spotting can be normal in the first trimester and at term as your cervix begins to change, but any more than a little spotting is a reason to call your midwife.
