Wait 3 minutes to confirm a "No Pregnancy" result.
It has a color-changing tip: The wide end turns pink for easy targeting.
How It Works:
When you are pregnant, your body produces the pregnancy hormone hCG (human chorionic gonadotropin). The hCG level doubles every 24 hours in the first few weeks, reaching a maximum of about 7 to 12 weeks of gestation.
Clearblue Pregnancy Tests work by detecting tiny amounts of pregnancy hormone in your urine and are more than 99% accurate from your expected start date.
