Can I Have a PAP Smear Test While on My Periods
Searching for “Pap smear test on my periods”? Here's the short answer: The NHS recommends booking your cervical screening for a time when you are not on your period, and if it starts on the day, you should contact your GP to rearrange. Sometimes the nurse can still go ahead, but heavy bleeding can make your result unclear.
A quick note on terms. The US name is Pap smear. In the UK, the same test is called cervical screening or a smear test, and this guide uses that term. Let's take a look.
Quick answer
Pick a day when you are not bleeding for your smear test.
If you have your period before your appointment, ring your GP surgery to make another appointment.
Mild spotting may be fine, and the sample taker will make the decision on the day.
Heavy bleeding can give an unclear result and require a retest.
You can have the test at any time if you are not having periods.
Can You Have a Smear Test on Your Period?
Technically yes, but it is advised to stay away. The NHS recommends booking an appointment when you are not on your period, and if your period falls on the day of your screening test, you should contact your GP to rearrange. Lloyds Pharmacy’s Online Doctor puts it like this: it’s not impossible to have a smear on your period, but menstrual blood can make the sample more difficult to analyse.
Public Health Wales has a pragmatic approach. On the day you bleed, your sample taker can have a look at your cervix and decide if they can take the sample.
Pap smear test on my periods: why blood causes trouble
The test involves a soft brush that collects a small sample of cells from your cervix. Those cells can be mixed with blood and make it more difficult for the lab to read. If the lab cannot read your sample, you will get an inconclusive result. This is called an inadequate result by the NHS, and you will usually be asked to come back in 3 months to repeat the test. Public Health Wales has a similar rule: a repeat in 12 weeks or more.
An unclear result doesn't mean that something is broken. It means the lab requires a cleaner sample. But another repeat means another appointment, another wait, and often more worry. A small timing switch can save all three.
What about spotting or light bleeding?
Light spotting is not the same as a full period. AXA Health says if you have light spotting and not a full period, you should normally be able to go ahead. The call is with Public Health Wales and the person who takes the sample and checks your cervix on the day. If you are spotting, let the nurse decide when you get there, and tell the receptionist.
When Is the Best Time for a Smear Test in Your Cycle?
You can have a smear test on any day that you are not bleeding. Lloyds Online Doctor suggests trying to time it in the second half of your cycle so the two weeks before you’re due next. AXA Health suggests mid-cycle, around 7 to 14 days after the first day of your period. The exact window varies between sources, so use this simple rule: book for the days after your bleeding stops and before the next one begins.
Simpler for two groups:
People with irregular periods. If you are not sure when your next period is due, Public Health Wales advises you should go ahead and book and attend.
Non-cyclical people. Lloyds Online Doctor says you can do the test whenever you want.
If you can't find a "perfect" slot, don't sweat it. “Better to be there than have the perfect day.”
What to Do If Your Period Starts Before Your Appointment
Everybody has a surprise period. Here’s how to do it:
“Check your flow. Heavy bleeding is more likely to produce an ambiguous result. Maybe OK, light spotting.
Book an early appointment at the practice or clinic. If you’re on your period on the day, the NHS says phone your GP to reschedule.
"Ask about the next slot." Ask for the first available appointment after your bleeding stops, ideally in a week or two.
Attend if you cannot rebook soon. If waiting would put you well past your invitation, ask the sample taker to assess on the day.
Do not miss it out. Rearranging is ok. Not cancelled and forgotten.
The NHS says if you missed an invitation, you can still book weeks or months later and do not have to wait for another letter.
How to Prepare for Your Smear Test
Some habits are good for your sample and your comfort.
Do:
Do not use vaginal medicines, lubricants and creams for 2 days before the test, as they can affect the results (NHS).
Wear something you can leave on, like a skirt or a long jumper.
If it helps, bring someone for support.
If you're nervous, tell the nurse. They can provide a smaller speculum, a different position, or a break.
Ask for a chaperone or for a longer appointment if you want them.
Don't:
Feel compelled to go on. You can ask to stop at any time.
Be ashamed of yourself. This is the work sample takers do daily.
What happens at the appointment?
The NHS explains the steps like this:
You go behind a screen to undress from the waist down and are given a sheet to wrap around you.
You lie down on a bed, normally with your knees bent and apart.
The nurse or doctor will gently insert a speculum into your vagina.
They open it and look at your cervix.
They take cells from your cervix with a soft brush.
They take away the speculum and leave you to dress.
The actual test is less than 5 minutes, and the whole appointment is about 10 minutes.
Bleeding After a Smear Test
Light bleeding or spotting may follow the test. The NHS says it should be over in a few hours. See a GP if you have heavy bleeding or if you have spotting for a few hours. Lloyds Online Doctor adds, "Your period shouldn’t be brought on early by a smear test.
Who Gets Invited and How Often
The NHS invites women and people with a cervix between 25 and 64 years of age for screening every 5 years. A couple of details matter:
Your first invitation arrives a few months before your 25th birthday.
If you have HPV, you may be invited earlier.
Screening stops at age 65 unless a recent test found an abnormality.
If you have had a total hysterectomy where your womb and cervix are removed, you do not need screening.
What your results mean
Your result tells you if human papillomavirus (HPV) was detected in your sample. This is the NHS summary:
HPV not detected. You have a very low risk of cervical cancer and will be invited again in 5 years.
HPV positive, no abnormal cells. You will be invited back in 1 year.
Abnormal HPV cells. You will be offered a colposcopy – a closer look at your cervix in hospital.
Vague outcome. You will be asked to do the test again in 3 months.
When Bleeding Means See a GP, Not Wait for Screening
Screening looks for early cell changes in healthy people. It is not a symptom diagnosis. If you have, the NHS advises you to see a GP without waiting for your next appointment if you:
bleeding between periods.
bleeding during or after sex; bleeding after menopause
abnormal vaginal discharge
Even if you’ve had a recent smear test, Public Health Wales advises the same. A new symptom does not override a recent normal result.Know More :Pap Smear and HPV Test
A Private Option for Cervical Screening
Others prefer private appointments, for example, if an NHS slot is out of their cycle. On the services page of the West London women’s health clinic, myGynaePlus, it lists smear tests with HPV and cytology, with results based in the laboratory. It also includes cervical screening and HPV follow-up as common reasons for consultation. It accepts self-referrals. According to the site, pelvic exams are explained and consented to and chaperoned. Appointment times differ, so ask about flexibility and work with your cycle. Ask your provider how and when you will receive your result.
Next Steps
Check your calendar, go over your invitation and schedule a day when you anticipate being bleed-free. If your period catches you unawares, call your surgery. If you have unusual bleeding, contact your GP; don’t wait for screening. Smear tests and HPV follow-up can be found at a clinic like myGynaePlus for a private appointment, but your GP remains the way to go for NHS screening. This information is general in nature. It is not a substitute for advice from your doctor or nurse.
FAQs About a Smear Test on Your Period
Can I have a Pap smear on my period?
You can, but the NHS advice is to book when you are not bleeding. Period blood can make it harder to read the sample. If your period starts on the day, contact your GP surgery to rearrange or ask the nurse if they can go ahead.
Does period blood affect smear test results?
Yes. Heavy bleeding could make it impossible for the lab to read your sample, leading to an unclear result. The NHS says you would usually do the test again in 3 months. An inconclusive result does not mean there is a problem.
What if I have spotting on the day of my smear test?
Some light spotting is not always a problem. AXA Health says usually you are good to go, and Public Health Wales says the sample taker checks your cervix and decides. When you get there, tell the nurse so she can assess.
How long should I wait after my period for a smear test?
There is no “one size fits all” amount of days. Book for a day when you’re not on your period. Some say the second half of your cycle, but any bleed-free day will do. Book irregular cycles.
Will I need to repeat my test if I go on my period?
Only if the lab can’t read your sample. If so, the NHS says you will be asked to take the test again in 3 months’ time; rearrange before the appointment and you prevent the repeat.
