If you suspect you might be pregnant, you're likely to feel restless and eager to find out. Many people, unable to contain their excitement, end up taking a pregnancy test earlier than the recommended time. However, this can be a pitfall! Premature testing has many disadvantages. Here, we'll explain the correct timing and mechanism of pregnancy tests.
What is a premature pregnancy test?
Typically, pregnancy tests can be used one week after the expected date of menstruation. Testing earlier than this is called "early testing." Testing earlier than the recommended time often results in an inaccurate reading, and the following disadvantages may apply.
- Even if there's a possibility of pregnancy, the test might be too early and be mistaken for a "negative" result.
- I wasted the pregnancy test.
- I learned about chemical pregnancy loss.
- I get depressed
Taking a pregnancy test too early is not recommended as it can easily cause emotional turmoil and stress. I completely understand the desire to know as soon as possible, but take a deep breath. It's important to wait until the appropriate time to use a pregnancy test.
How pregnancy tests work
After a fertilized egg implants, chorionic villi, the precursors of the placenta, begin to grow within a few days. The hormone hCG (human chorionic gonadotropin) secreted from these villi is present in the mother's urine and is what causes pregnancy tests to react.
The secretion of the "hCG hormone" starts in small amounts but then increases rapidly, peaking around the second to third month of pregnancy. Secretion continues throughout pregnancy, protecting the baby in the womb, maintaining the secretion of progesterone and estrogen, and promoting placental growth.
When do you find out you're pregnant?
The hormone hCG begins to appear in urine about 3-4 days after implantation of a fertilized egg. In some cases, it may be detectable a few days before the next expected menstrual period. However, for accurate detection, the ideal time to test is one week after the expected menstrual period, when hCG levels have increased. In other words, the ideal time to test is "the start date of your last menstrual period + your menstrual cycle + one week." If you don't know the start date of your last menstrual period or your menstrual cycle, you can think of it as "three weeks or more after the day you had sex."
