Could a not pregnant reading on Clear Blue Digital pregnancy test be inaccurate when period is 48 hrs late and did in afternoon having drunk cup of tea glass water long before?

There are a few possible reasons why you may have received a negative reading on a Clear Blue Digital pregnancy test, even though your period is 48 hours late.

1. The pregnancy hormone (hCG) levels may not be high enough to be detected by the test: Typically, hCG levels start to rise rapidly after conception, but it may take a few days for them to reach a level that is detectable by a home pregnancy test. If you tested too early, it's possible that hCG levels were still too low to be picked up by the test.

2. The test may have been used incorrectly: Be sure to carefully read and follow the instructions provided with your pregnancy test. Make sure you are using the test within the expiration date, and that you are using it correctly.

3. The reading may have been affected by the cup of tea and glass of water you consumed: Consuming fluids before taking a pregnancy test can dilute the urine, which may affect the accuracy of the test. It is recommended that you do not drink excessive amounts of fluids before taking a pregnancy test, and that you try to urinate no sooner than 3-4 hours after consuming fluids.

4. There may be an underlying medical condition: In some cases, a delayed period or a negative pregnancy test result can be caused by an underlying medical condition, such as hormonal imbalances or thyroid issues. If you continue to experience a delay in your period and receive negative pregnancy test results, it's important to see a doctor for evaluation.
