Introduction
You can determine whether you are pregnant through symptoms, early pregnancy test strips, or blood tests after having unprotected sex. A significantly delayed menstrual period increases the likelihood of pregnancy. Using a pregnancy test strip on first-morning urine, two lines—whether one dark and one light, or both distinctly red—indicate a positive result confirming pregnancy. Drawing venous blood to measure human chorionic gonadotropin (hCG) levels, if elevated and doubling every other day, confirms pregnancy.

Generally, you can determine whether pregnancy has occurred after unprotected sex by observing symptoms, using a home pregnancy test, or undergoing blood tests.

1. Observing Symptoms

For women with regular menstrual cycles, if no contraceptive measures were taken during intercourse, one way to assess possible pregnancy is by monitoring the arrival of menstruation. A significantly delayed period increases the likelihood of pregnancy.

2. Home Pregnancy Test

Using a quality-assured early pregnancy test strip from a reputable manufacturer to test first-morning urine can also help determine pregnancy. The number and intensity of colored bands on the test indicate results. If two lines appear—whether one dark and one faint, or both distinctly red—pregnancy is likely confirmed.

3. Blood Test

Testing for human chorionic gonadotropin (hCG) levels in venous blood is a highly accurate method for confirming pregnancy. If other methods fail to provide a clear result, visiting a reputable hospital for a blood test is recommended. Significantly elevated hCG levels that double approximately every 48 hours strongly indicate pregnancy.

In addition, abdominal ultrasound can also be used to confirm pregnancy. If home testing fails to provide a definitive answer, it's advisable to seek prompt medical evaluation. Once pregnancy is confirmed, regular prenatal checkups under a doctor’s guidance are essential.
