When Should I Take a Pregnancy Test?

If you suspect you might be pregnant, taking a pregnancy test is the first step to confirming it.

Knowing when to take the test, the types of pregnancy tests that are available, and how they work can help you get accurate results.

Here’s a guide to help you understand pregnancy tests and when to use them. (Looking for free pregnancy testing near you? Contact First Concern today to schedule your free, confidential appointment.)

When to Take a Pregnancy Test

The best time to take a pregnancy test is after you’ve missed your period. This is because pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG), which is produced after a fertilized egg attaches to the uterine lining. HCG levels build up quickly but are most detectable after a missed period.

If you have a regular cycle and your period is late, taking a test at this point will give you the most reliable results. Those with irregular cycles should wait at least two weeks after unprotected sex, as this gives your body enough time to produce detectable levels of hCG.

Types of Pregnancy Tests

There are two main types of pregnancy tests: urine tests and blood tests.

Urine Tests: Urine tests are the most common type of pregnancy test and can be done at home or at a doctor’s office. These tests detect hCG in your urine. Home pregnancy tests are easy to use—either by holding the test stick in your urine stream or dipping it into a collected sample. Results typically appear within a few minutes, usually as lines, plus/minus symbols, or digital readouts like “pregnant” or “not pregnant.” Most home tests can detect pregnancy about a week after a missed period, but testing with first-morning urine, which is more concentrated, can improve accuracy.
Blood Tests: Blood tests are performed by healthcare providers and can detect pregnancy earlier than urine tests, about 6-8 days after ovulation. There are two types of blood tests:
- Qualitative hCG Test: This test confirms whether or not hCG is present in the blood, much like a urine test.
- Quantitative hCG Test: This measures the exact amount of hCG in the blood. It provides more detailed information about the pregnancy and helps monitor its progression.
