When it comes to determining the best time to take a pregnancy test, several factors need to be considered, especially if you are unsure about your menstrual cycle. Based on the information provided, it appears that your menstrual cycle is relatively regular, with your last periods occurring on October 21, November 15, and December 15. Given that your app predicts your next period would be due on January 12, but you have not yet started your period by January 16, this is a crucial indicator for testing.

The most accurate time to take a pregnancy test is typically after a missed period. In your case, since your period was expected on January 12 and you have not seen it by January 16, you are already in a position to test. Home pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin) in your urine, which is produced shortly after a fertilized egg attaches to the uterine lining. This usually occurs about 6 to 12 days after conception, which aligns with your timeline of having unprotected intercourse on December 31 and January 1.

For the best results, it is recommended to take the pregnancy test first thing in the morning when your urine is most concentrated. This increases the likelihood of detecting hCG if you are pregnant. If the test is negative but your period still does not arrive, it is advisable to wait a few days and test again, as sometimes hCG levels may not be high enough to detect early in pregnancy.

In addition to the timing of the test, it is essential to consider the symptoms you are experiencing. You mentioned having symptoms that are typically associated with an impending period, such as abdominal discomfort and mood changes. These symptoms can sometimes mimic early pregnancy signs, which can lead to confusion. If you continue to experience these symptoms without the onset of your period, it may further indicate the need for a pregnancy test.

If you receive a positive result, it is advisable to schedule an appointment with your healthcare provider to confirm the pregnancy and begin prenatal care. Conversely, if you receive a negative result and your period still does not arrive, it would be wise to consult with a healthcare professional to explore other potential reasons for the missed period, such as hormonal imbalances or stress.

In summary, the best time to take a pregnancy test is after your expected period has missed, which in your case is now. Testing in the morning with a concentrated urine sample will yield the most accurate results. If you have any uncertainties or if your symptoms persist, seeking medical advice is always a prudent step.
