The short explanation
A Pap smear can be done during pregnancy, and many clinicians consider it fine, especially in the first few months. The sample is taken from the outside of the cervix and does not reach the baby. Some women have light spotting afterwards because the cervix has more blood flow in pregnancy. Some screening programmes, like the UK's, prefer to wait until about three months after delivery for routine screening, unless a previous result was abnormal. So whether to test now or later is a decision for you and your obstetrician.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- If you had an abnormal result before and are due for follow-up, testing during pregnancy may be advised, so that any changes can be watched.
- If the doctor finds changes, colposcopy can still be done in pregnancy. Treatment is usually delayed until after delivery unless there is concern about cancer.
- Tell the person doing the test that you are pregnant.
- Light spotting after the test can happen, but bleeding in pregnancy should always be mentioned to your doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot say whether you should test now or after delivery. Your obstetrician can decide based on your history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Should I have my smear now or after delivery?
- Is light spotting after the test expected?
- If changes are found, what happens during pregnancy?
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 fainting in pregnancy.
Get help the same day
- Get care the same day for any bleeding in pregnancy that is more than light spotting after the test.
Raise it at a routine appointment
- Discuss screening timing at your next antenatal visit.
