The short explanation
It is usually best to reschedule. Blood can make it harder for the lab to see the cervical cells clearly, which sometimes means the sample cannot be read and the test has to be repeated. Many clinics suggest booking for about a week after your period ends and before the next one is due. If you are near the end of your period and bleeding is very light, some clinics, especially those using liquid-based or HPV tests, may still go ahead. A quick phone call to the clinic can save a wasted trip.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- If you were booked because of a symptom such as bleeding after sex or bleeding between periods, do not simply delay. Ask the clinic whether the doctor still wants to see you, as an examination may be useful even if a sample is not taken.
- If rescheduling is hard because of travel, work or a camp that will not return soon, explain this to the clinic.
- Avoid sex, vaginal creams and douching for a day or two before the new appointment.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot say whether your clinic's test can be done during bleeding. That depends on their method.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Can the test still be done with light bleeding?
- When is the best time in my cycle to rebook?
- If my appointment was for a symptom, should I still come?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- If your appointment was booked because of bleeding after sex, bleeding between periods or unusual discharge, see a clinician within a few days even if the smear itself is postponed.
Raise it at a routine appointment
- Rebook for a date away from your period, and keep track of the new date.
