Direct answer: For most Clearblue tests, you should wait until enough time has passed for pregnancy hormones to be detectable. This usually means testing after a missed period or about 2 weeks after unprotected sex if your cycle is regular, and longer (about 3 weeks) if your period is irregular or you’re unsure. Details and guidance
- Why waiting helps: Pregnancy tests detect hCG, which rises after implantation. Testing too early can yield a false negative because hCG levels may not be high enough yet.
- If your cycle is regular: Aim to test about 2 weeks after unprotected sex, which is around the time you expect your next period. If your period is late, you can test then.
- If your cycle is irregular or you don’t know when to expect your period: It’s often best to wait at least 3 weeks after unprotected sex or test after you’ve missed a period. Some Clearblue tests advertise that they can be used several days before a missed period, but their accuracy is highest after you’ve missed your period.
- Early-detection considerations: Some ultra-early tests can detect lower levels of hCG earlier, but their accuracy is still lower before a missed period. A negative result taken very early may need to be repeated a few days later if your period hasn’t started.
- Practical tips:
- Use the first-morning urine for best concentration if you’re testing before a missed period.
- Follow the package instructions carefully for timing and reading the result.
- If you get a negative result but still suspect pregnancy (missed period, symptoms), retest a few days later or contact a healthcare provider for a blood test or clinical confirmation.
- If the result is positive, follow the instructions on the box and seek medical care to confirm and begin prenatal care.
