1. Misread the results:
- False positive: A faint line can sometimes appear due to evaporation, especially after the recommended reading time. - False negative: Not waiting long enough for the results or using an expired test can lead to false negatives.
2. Chemical or ectopic pregnancy:
- Chemical pregnancy: An early pregnancy that miscarries before the embryo implants in the uterus. - Ectopic pregnancy: A pregnancy that develops outside of the uterus, which can be detected by a blood test.
3. Medical conditions:
- Thyroid disorders - Certain medications, such as fertility treatments or hormone replacement therapy - Recent miscarriage or abortion
4. Other factors:
- Testing too early or too late in the day: Hormone levels fluctuate throughout the day. - Dehydration: Diluting urine can affect the test results. - Some medications or supplements: Certain substances can interfere with the test.
Steps to take if you have 2 invalid pregnancy tests:
- Repeat the test using a different brand or a digital test. - Call your healthcare provider for a blood test to confirm pregnancy. - If you suspect a chemical or ectopic pregnancy, seek medical attention immediately.
