When is the earliest time to take a pregnancy test?
Dear Doctor: My period started on April 23 and again on May 17, with sexual intercourse in between.
When should I expect my period in June? Additionally, if I am pregnant, when is the earliest I can take a pregnancy test to find out if I am pregnant? Thank you, Doctor.

When it comes to determining the right time to take a pregnancy test after a missed period, there are several factors to consider. Based on your menstrual cycle, if your last period started on April 23 and your next one was on May 17, we can estimate your cycle length and predict when your next period might be due. If you typically have a cycle of around 28-30 days, your next period would likely be expected around June 17 to June 19.
If you have had unprotected intercourse during this cycle, and your period does not arrive by the expected date, it is advisable to take a pregnancy test. The best time to take a home pregnancy test is at least one week after your missed period. This timing allows for the hormone human chorionic gonadotropin (hCG) to build up in your urine to a detectable level. Most home pregnancy tests are designed to detect hCG levels accurately when taken after a missed period, which typically occurs about two weeks after conception.
If you suspect you might be pregnant before your missed period, some sensitive tests can detect pregnancy as early as 6-8 days after ovulation, but these tests may not be as reliable. Testing too early can lead to false negatives, as the hormone levels may not be high enough to detect. Therefore, if you take a test before your missed period and it shows negative, but you still suspect pregnancy, it is wise to wait a few days and test again.
In your case, if your period is late in June, you should take a pregnancy test around June 24 or later for the most accurate result. If the test is positive, it is recommended to schedule an appointment with your healthcare provider for confirmation and to begin prenatal care. If the test is negative and your period still does not arrive, you should consult with your doctor to explore other potential reasons for the missed period, such as hormonal imbalances or stress.
In summary, the best practice for taking a pregnancy test is to wait until at least one week after your expected period. If you have any symptoms of pregnancy, such as nausea, breast tenderness, or fatigue, these can also be indicators, but they are not definitive without a test. Always remember that if you have concerns about your menstrual cycle or potential pregnancy, reaching out to a healthcare professional is a good step for personalized advice and care.
