How long does it take to detect pregnancy and how long does it take to react

Many girls are unable to find out they are pregnant right away, and may not even know it for several months. Most girls only think they are pregnant when they see their menstrual period is delayed. So we need to understand how long it takes to detect pregnancy? How long does it take to have a reaction?

It is not easy to detect pregnancy at the beginning of pregnancy. It can be detected about 7 days after fertilization and implantation. However, some people have irregular menstruation and sometimes have delayed menstruation. A positive result with early test paper does not mean that you are not pregnant. You can retest it after a few days. It will be more obvious in 1-2 weeks of pregnancy. It is best to use morning urine, which is more accurate. Basically, you can detect whether you are pregnant. Generally speaking, in the early stages of pregnancy, women will experience a series of early pregnancy reactions such as dizziness, nausea, drowsiness, and breast swelling. Generally, they will become more obvious 10-14 days after pregnancy and will disappear on their own after three months. Therefore, if a woman has the above symptoms, she can use early pregnancy test paper and pregnancy test stick to test pregnancy. The working principle of early pregnancy test paper pregnancy self-test is to detect the hCG value, that is, the value of human chorionic gonadotropin. This hormone will be excreted into the urine through the blood circulation of pregnant women. Early pregnancy test paper pregnancy self-test is a more convenient and quick method of early pregnancy detection. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning and it becomes increasingly obvious after 10 to 14 days.

Generally speaking, early pregnancy reactions begin to appear around 40 days into pregnancy. This is because the hormones in women’s bodies increase after pregnancy, which leads to a series of early pregnancy reactions of varying degrees, such as amenorrhea, nausea, vomiting, loss of appetite, drowsiness, exhaustion, dizziness, headache, breast tenderness, increased vaginal discharge, etc. The degree of early pregnancy reactions varies from woman to woman due to different physical conditions. Usually, these early pregnancy reactions gradually disappear after 3 months of pregnancy. It is recommended that women should rest in bed as much as possible after pregnancy, avoid fatigue, and take more foods rich in vitamins and proteins. They should pay attention to balanced nutrition and avoid eating too spicy or greasy foods to avoid aggravating early pregnancy reactions.

If a woman has sex without taking any contraceptive measures and has amenorrhea, the first thing she should consider is the possibility of pregnancy. This is of course for women with regular menstruation. Generally, you can test whether you are pregnant three days after amenorrhea. Of course, if you test again after more than a week, the accuracy will be higher. Generally speaking, women's menstruation is unstable sometimes. If it is delayed for about a week, it is relatively normal, but if it is more than a week, it may be pregnancy. At this time, you can check yourself to determine whether you are pregnant. Of course, you should also pay attention to the fact that if you diet excessively and have a little mental stress during this period, it will also cause menstruation to be delayed. It is best to go to the hospital for examination and verification. Women are very prone to miscarriage in the first period of pregnancy, because the fetus is relatively unstable at this time, so mothers need to do a good job of meticulous pregnancy care. Of course, this first requires knowing whether you are pregnant.

If the menstrual cycle is regular, the embryo can be seen at about six weeks of pregnancy through ultrasound examination, and the primitive cardiovascular pulsation can be seen at about seven weeks of pregnancy. If the menstrual cycle is longer or the ovulation is delayed, the fetal heart may appear, and the time of the embryonic bud will be postponed. However, generally through abdominal ultrasound examination, if the diameter of the gestational sac on abdominal ultrasound is greater than 2.5 cm, there is still no fetal heart, or through vaginal ultrasound examination, the diameter of the gestational sac is greater than 2.0 cm, and there is still no primitive cardiovascular pulsation, it is considered that the embryo has stopped developing. Early embryonic development is mostly caused by chromosomal abnormalities in the fertilized egg.
