Implantation bleeding is the most common early sign of pregnancy, which you may experience. It looks like a light bleeding or spotting, which may occur, approximately, between the sixth and the twelfth days after ovulation, at the moment when the fertilized egg implants itself in the uterus. If you see a bloody discharge in the middle of your cycle, you should always visit your doctor, to get to know the exact causes of it and then act accordingly to the situation.
The Causes of Implantation Bleeding?
When an egg comes out of the ovary, it travels through the Fallopian Tube to the uterus. If during this journey it finds a viable spermatozoon, it becomes fertilized. The next step after conception is a cell division. Your baby starts developing immediately after the egg has been fertilized, dividing for the first time during the initial twelve hours of life. From this point until the formation of the fetus, the ovum can be called embryo. The number of cells in the embryo is multiplying each twelve hours. This happens while the zygote moves through the Fallopian Tube, still traveling to the uterus. By the third day, conceptus looks like a ball of cells even smaller than a grain of rice. Now the fertilized egg can be called blastocyst. It is a structure comprised of up to three hundred cells about 0.1 or 0.2 millimeters in diameter. The inner layer of the blastocyst will eventually become the fetus, while the external layer will become the placenta that will nourish and protect the baby during all pregnancy.
