We don’t usually take smears in pregnancy but sometimes a smear is taken before you realise you are pregnant. At other times you may have had an abnormal smear before the pregnancy and your doctors may want to keep a check on things whilst you are pregnant. An abnormal smear in pregnancy can be easily managed without causing any harm to the pregnancy.
If the smear shows a very low grade abnormality, technically called “borderline nuclear atypia,” we would usually recommend repeating the smear in 6 months time. In pregnancy this can be left safely until 3 months after delivery, if this is your first abnormal smear and you have had regular smears up until then.
If the smear shows any other abnormality we recommend colposcopy. This just means having a careful look at the cervix with magnification and will not harm the pregnancy. A biopsy is not usually necessary during pregnancy. Depending upon the abnormality your doctor may suggest you have further colposcopies during pregnancy but usually we leave treatment until about three months after delivery.
The most important thing is not to get too worried by the smear result but just to follow the advice you are given and get it checked out.
