However, approximately 70% of women are uncertain of their last menstrual period3.

The Clearblue Advanced Pregnancy Test with Weeks Estimator gives an estimate of time since ovulation (1-2 weeks, 2-3 weeks, 3+ weeks) relative to the LH surge.4

How It Works

The Clearblue Advanced Pregnancy Test with Weeks Estimator contains two measurement strips – a low-sensitivity strip and a high-sensitivity strip. These work together to detect pregnancy and to identify hCG levels (pregnancy hormone) to estimate the number of weeks since ovulation (1-2 weeks, 2-3 weeks, 3+ weeks). The high-sensitivity strip detects low levels of hCG, expected in early pregnancy, and the low-sensitivity strip detects higher levels of hCG, typical when pregnancy is more than 3 weeks since ovulation (1-2 weeks, 2-3 weeks, 3+ weeks).

An optical reader inside the test stick is used to measure the results lines and give you a simple, digital readout in words and numbers. If the test is negative, your result will read 'Not Pregnant'. If the test is positive, 'Pregnant' will be clearly indicated in words on the display along with an estimate of the number of weeks since ovulation: 1-2, 2-3 or 3+. Your doctor determines how many weeks pregnant you are based on the first day of your last menstrual period and ultrasound results. This test provides a different estimate that cannot be substituted for a doctor's determination of gestational age. Be sure to see your doctor if your result is positive.
