Does the pregnancy test stick show the correctness of pregnancy?

Many women will choose to take a pregnancy test when they find that their menstruation has not arrived as expected. The most common method is to use a pregnancy test stick. Regardless of whether pregnancy is detected or not, I believe everyone has a question: are the results of the pregnancy test stick accurate? Is the pregnancy test stick used correctly? Let's talk about this issue below.

First of all, how long does it take to detect pregnancy? Many sisters who are preparing for pregnancy are always looking forward to it after having sex, and they wish they could know immediately whether they are pregnant after having sex. However, pregnancy cannot be detected in a short time. When and how to test it is the most scientific and reasonable? How many days after conception can it be detected? First of all, we need to know that after pregnancy, the first change that occurs compared to before pregnancy is the change in hormones in your body. The most important thing is human chorionic gonadotropin, or HCG for short, which is a hormone secreted by the placenta.

Starting from 10-14 days after conception, human chorionic gonadotropin is secreted by the placental chorionic trophoblast cells to help the formation of the placenta; it also inhibits ovarian ovulation and promotes the secretion of progesterone and estrogen to stimulate the smooth formation of the placenta.

In the early stages of pregnancy, the HCG concentration will continue to increase, increasing 1.5 times every two days, but it will not increase continuously. It will reach its peak around the 12th week and then show a decreasing trend until the end of pregnancy.

When using a pregnancy test stick to detect pregnancy, you must understand that HCG in urine is actually secreted in large quantities after the ovum is implanted, and it takes at least 11 days for the ovum to implant. Therefore, when using a pregnancy test stick to detect pregnancy, you usually have to wait until 11 days after ovulation. The time is later than the blood test. The accuracy rate of pregnancy test sticks from regular brands is about 80%. It should be noted that your operation of the pregnancy test stick and the different sensitivities of different brands of pregnancy test sticks may cause deviations in the results.

I believe that women who have enough time to prepare for pregnancy have already prepared a lot of pregnancy test tools, and even learned how to prepare for pregnancy using ovulation test strips. Of course, in addition to testing ourselves, we still need to go to the hospital for a confirmed diagnosis, which is usually done through blood tests, urine tests or B-ultrasound.
