When does implantation bleeding usually occur during pregnancy?

At the beginning of pregnancy, pregnant women will experience the stage of embryo implantation. At this time, a small number of pregnant women will bleed, but not all pregnant women will suffer from bed bleeding. But they don't know whether implantation bleeding will end immediately or continue for a while. If it continues for a while, when does implantation bleeding usually end?

How many days does implantation bleeding last?

It occurs about 6 days after insemination. At this time, most pregnant women do not have very obvious reactions, and a few women will have some bright red or light pink blood stains, which is called implantation bleeding. This condition does not occur in everyone, so it is not a noticeable pregnancy symptom. Implantation bleeding occurs about 1 week into pregnancy. If it is now 7-10 days since ovulation, then it can be suspected that the embryo has implanted. You can see a doctor for examination. If it is more than 12 days since ovulation, it may be menarche.

How many days does it take for the embryo to implant?

Embryo implantation refers to the process in which the early test tube embryo of viviparous mammals fuses with the endometrium of the pregnant mother, thereby establishing a structural connection between mother and child to maintain material exchange. After embryo implantation, the test tube embryo absorbs nutrients from the pregnant mother's blood and continues to grow and develop. Embryo implantation is a comprehensive process that requires preparation and cooperation from both mother and daughter. The time of pregnancy refers to the time of embryo implantation, and the beginning time of embryo implantation is about 3 days after the couple's sexual life.

Embryo implantation begins around the 6th to 8th day after fertilization and continues until the 11th to 12th day. Generally, the embryo implants slightly more on the posterior wall of the uterus than on the anterior wall, with the center line exceeding the outer wall. After the embryo implants, the body begins to secrete a hormone that is unique to pregnant women. If this is measured in the blood, it must be measured at least 7 days after ML. There is no feeling of embryo implantation. Pregnancy can only be considered after the fertilized egg successfully implants in the uterus. On the fourth day, the physiological needs of pregnancy have just begun, the enzyme system during pregnancy has not been activated, and metabolic substances have not accumulated. The detection sensitivity of the pregnancy test paper cannot achieve a clear identification effect. If you use a pregnancy test strip, it will take at least 15 days. If your period is delayed by a week, the test will be more accurate.
