1. What is Clear Blue Pregnancy Test?

Clear Blue is a popular brand of home pregnancy tests that detects the presence of human chorionic gonadotropin (hCG) in urine. The test provides accurate results when used at the recommended time after conception.

2. How Does the Calculator Work?

The calculator uses Clearblue's recommended test timing formula:

Where:

• LMP — Last Menstrual Period (start date)
• 10-14 days — Recommended testing window after LMP

Explanation: This timing ensures sufficient hCG levels are present in urine for accurate detection by the Clearblue test.

3. Importance of Test Timing

Details: Testing too early may result in false negatives due to insufficient hCG levels. Following the recommended timing maximizes test accuracy and reliability.

4. Using the Calculator

Tips: Enter the first day of your last menstrual period. The calculator will provide the optimal testing window (10-14 days after LMP) for most accurate results with Clearblue tests.

5. Frequently Asked Questions (FAQ)

Q1: Why test 10-14 days after LMP?
A: This timeframe corresponds to when hCG levels are typically high enough to be detected by home pregnancy tests.

Q2: Can I test earlier than recommended?
A: While possible, testing earlier increases the risk of false negative results due to low hCG levels.

Q3: What if my cycle is irregular?
A: For irregular cycles, use the longest cycle length you've experienced in the past 6 months to estimate LMP.

Q4: When is the best time of day to test?
A: First morning urine typically contains the highest concentration of hCG for most accurate results.

Q5: How accurate are Clearblue tests?
A: When used according to instructions at the recommended time, Clearblue tests are over 99% accurate.
