Pap smears and pregnancy testing
A Pap smear checks cervical cells. It cannot detect pregnancy.
If your period is late or you think you could be pregnant, you need a pregnancy test that measures hCG in urine or blood. A Pap result cannot tell you whether you are pregnant.
Learn what each test checks, when to take a pregnancy test, and what to know about cervical screening during pregnancy.

What does a Pap smear actually check for?
A Pap smear, also called a Pap test or smear test, screens for abnormal cells on the cervix, including precancerous changes. A clinician collects a small sample of cervical cells and sends it to a laboratory. [1]
It does not measure human chorionic gonadotropin, or hCG, the hormone detected by pregnancy tests.
Is a Pap smear the same as an HPV test?
No. A Pap test looks for cell changes. An HPV test looks for high-risk human papillomavirus that can cause those changes. The tests may be performed together, but neither detects pregnancy. [1]
A Pap smear is also not a general test for sexually transmitted infections. If you have symptoms or a possible exposure, ask which separate tests you need.
Understanding your tests
Pap smear vs. pregnancy test: what is the difference?
On smaller screens, swipe across the table to view all columns.
| Test | What it checks | Detects pregnancy? |
|---|---|---|
| Pap smear | Abnormal cervical cells | No |
| HPV test | High-risk HPV | No |
| Urine pregnancy test | hCG in urine | Yes, when enough hCG is present |
| Blood pregnancy test | hCG in blood | Yes; may detect lower levels earlier |
A blood pregnancy test may report whether hCG is present or measure its amount. Your clinician decides whether blood testing is useful based on timing, symptoms, and medical history. [2]
An hCG result alone does not establish where a pregnancy is located or whether it is developing normally. Follow-up may include repeat blood tests or ultrasound, depending on your situation.
Pregnancy testing timeline
When should you take a pregnancy test?
Most home pregnancy tests can be used from the first day of a missed period. If you do not know when your period is due, test at least 21 days after your last unprotected sex. [3]
Step 1
Check the timing
Consider when your period was due and when pregnancy could have occurred.
Step 2
Use a pregnancy test
Follow the instructions for your test, including when to read the result.
Step 3
Review the result
A negative result may need repeating if you tested early or your period remains late.
Step 4
Arrange follow-up
Contact your provider about a positive result, persistent symptoms, or ongoing uncertainty.
What if your pregnancy test is negative but your period is late?
Testing too early can produce a negative result even when you are pregnant. If pregnancy is still possible, repeat the test after a few days. Contact your provider if another test is negative and your period still has not arrived. [3] [4]
Do not use a normal Pap result to rule out pregnancy. A Pap smear and a pregnancy test are separate tests, even if they are ordered during the same appointment.
What should you do after a positive result?
Contact your provider to discuss next steps and arrange care. Read our guide to when to visit the doctor to confirm pregnancy .
Can you have a Pap smear while pregnant?
Yes. A Pap smear can be performed safely during pregnancy if you are due for cervical screening. Your provider can review your screening history and determine whether testing is needed. [5]
Tell your provider before the exam if you are pregnant or think you could be. Pregnancy does not automatically mean you need another Pap test if screening is already up to date.
Can a Pap smear cause spotting during pregnancy?
Light spotting can happen after sampling because the cervix may bleed more easily during pregnancy. Contact your care team about bleeding, especially if it is persistent, heavy, or accompanied by pain. [5]
Understanding your result
What if your Pap result is abnormal during pregnancy?
An abnormal result does not automatically mean cancer, and it does not mean the Pap smear detected pregnancy. It means cervical cell changes were found and follow-up may be needed.
Follow-up depends on the result, previous screening history, and estimated risk. A closer examination called colposcopy, sometimes with a biopsy, may be recommended during pregnancy. Do not assume every abnormal result can wait until after delivery. [6]
Can a pelvic exam tell if you are pregnant?
A clinician may notice changes that raise the possibility of pregnancy, but a pelvic exam does not replace pregnancy testing. Tell your provider about your last period, symptoms, contraception, and any home test results.
Symptoms such as nausea, breast tenderness, or fatigue cannot confirm pregnancy on their own. If pregnancy is possible, use a pregnancy test.
When to seek care
Do not wait for test results if you have urgent symptoms
Seek urgent medical assessment if pregnancy is possible and you have one-sided lower abdominal pain, vaginal bleeding, or shoulder-tip pain. These can be symptoms of an ectopic pregnancy, including before you have a positive pregnancy test. [7]
Call 911 or go to an emergency department for sudden severe abdominal pain, fainting, severe dizziness, or heavy bleeding. Do not wait for Pap results or another home pregnancy test.

Frequently asked questions
Can a Pap smear detect early pregnancy?
No. A Pap smear checks cervical cells, not hCG. Pregnancy is assessed with a urine or blood pregnancy test.
Does a normal Pap smear mean I am not pregnant?
No. A normal Pap result describes the cervical cells collected. It does not rule pregnancy in or out.
Will my doctor automatically test for pregnancy during a Pap smear?
Do not assume so. Pregnancy testing is separate. Tell your provider pregnancy is possible and ask which tests are being ordered.
Can a Pap smear cause a miscarriage?
A routine Pap smear is considered safe during pregnancy and does not cause miscarriage. Light spotting may occur afterward. Contact your care team about bleeding or pain.
Does an abnormal Pap result mean I am pregnant?
No. It means cervical cell changes were found and follow-up may be needed. Pregnancy is assessed separately.
Should I cancel my Pap appointment if I might be pregnant?
Contact the office before canceling. Your provider can review your screening history, discuss pregnancy testing, and determine whether cervical screening is due.
