How many days of pregnancy does one deep and one shallow have

Female friends who often use pregnancy test sticks and become pregnant later should have encountered the following situation: one indicator on the pregnancy test stick is dark and the other is light. At this time, some worried friends will go to the hospital for blood tests, while others will measure again after a few days, and when they measure again, they find that the light one has also become darker. This means that you are likely to become a mother. So if the pregnancy test stick shows dark and light, how many days of pregnancy will it actually be?

How many days of pregnancy does one deep and one shallow actually have

1. A weak positive result on the pregnancy test paper may indicate pregnancy, but it cannot completely prove that you are already pregnant, nor can it indicate how long you have been pregnant. You need to go to the hospital to test hcg to confirm whether you are pregnant.

2. Pregnancy is calculated from the first day of the expected delivery date, not from the day of intercourse.

How long does it take for a pregnancy test stick to detect whether or not you are pregnant? The ovulation period is around the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it will take 6 or 7 days for the combination of sperm and egg to produce HCG. Pregnancy test sticks are all determined by testing urine HCG. HCG actually starts to secrete in large quantities after the fertilized egg implants, and the transformed trophoblasts begin to secrete and produce HCG in large quantities. It takes at least 11 days for the fertilized egg and embryo to implant. Therefore, to use the pregnancy test stick to detect whether you are pregnant or not, it only takes 6 days at the beginning. Of course, if you want to be more precise, wait 11 days, then it will be more accurate.

The result of pregnancy (positive type) can be judged after 1 minute (30 seconds at the fastest), which means that if two lines are clearly displayed after 1 minute of the test, it shows the result of pregnancy (positive type) and there is no need to wait until 3 minutes later to judge.

The result of not being pregnant can only be confirmed after 3 minutes. This is because in the early stages of pregnancy, the HCG hormone content in the urine is very low, and a weak positive result may appear during the test. The weak positive result may not be displayed after 1 minute. With the increase in reaction speed, it will take 3 minutes for two lines to be displayed. At this time, the appearance of two lines should still be judged as a pregnancy (positive) result. If there is still only one comparison line after 3 minutes, it can be judged as not pregnant (negative).

What is the probability of pregnancy if the pregnancy test stick shows one dark and one light?

Pregnancy test sticks are a well-known early pregnancy test tool for many young women. Generally speaking, the accuracy of pregnancy test sticks from reliable and well-known brands is about 85% to 95%. Therefore, the pregnancy test stick is not 100% accurate. If the contrast line is obviously clear and the test line is very light, it means that you may be pregnant, but it does not necessarily mean that you are pregnant. In this case, you need to test again every two days with a new pregnancy test stick to collect morning urine. If you want to confirm whether you are really pregnant, you should go to the hospital for more accurate examination. .
