Implantation bleeding, implantation bleeding or period

When does implantation bleeding occur

When does implantation bleeding occur answers this question and new artciles for when does implantation bleeding occur. Bleeding implantation is a slight bleeding that occurs 10 days after ovulation (approximately), when the fertilized egg is implanted in the uterus or nests.

Even if your baby has just been conceived begins to “work” immediately in their development. The next step after fertilization, cell division. In the first 12 hours, the cell zygote divides into two cells and these in turn are divided into two and this division continues and the number of cells doubles every 12 hours. All this happens while the zygote moves through the fallopian tubes and into the uterus. At about three days and is a cluster of cells that looks like a tiny raspberry. At this time the developing baby is called a “morula” and you’re ready to leave the fallopian tube into the uterus.

In four or five days after conception or fertilization of an egg, your developing baby, which by that time it has about 500 cells, reaches its destination in the uterus. It has changed from a cell mass of a group of cells located around a fluid-filled cavity. At this point is called a blastocyst. The inner layer of the blastocyst is a compact mass of cells (but be amazed, each of them knows exactly what their function) that develop into a baby. In the outer layer of cells (called “trophoblast”), will form the placenta whose fate will be to nourish the developing baby.

Once the blastocyst reaches the uterus, it sticks to the wall until it starts producing enzymes that will help you “digest” the lining of the uterus and allow it to nest there. This usually comes a week after fertilization, that is, by day 12, the blastocyst is already firmly embedded in their new “home.” It adheres firmly to the endometrium where they draw on the mother’s blood.

At this point, you’re pregnant but it is still too early to have missed a period or to have any other symptoms of pregnancy. In these first days after fertilization abortions are very common even before you find out you’re pregnant. Scientists believe that 3 out of 4 of these abortions occur in the time of implantation. The cause may be infection or exposure to toxic substances (at the moment this kind of problems can cause an abortion but not a baby with birth defects). However, the majority of pregnancy losses at this time is due more to errors in the process of development that are not anyone’s fault.

Pregnancy loss at this point was 13% when the implantation was made the 9th day and was increased by 26% when the implantation was after the 10th day after fertilization, increased 52% when the implantation was in the 11th day after fertilization and 82% when the implantation was 11th day after fertilization.

Approximately one third of pregnant women submitted spotting or bleeding during implantation. This bleeding can occur in one pregnancy, two, or all of your pregnancy, there is no written rule.
