This question is asked by many women who have had one or more pregnancies, most commonly by those who claim to have never experienced it during pregnancy. Many doctors advise that implantation bleeding is generally an exception and is usually an uncommon and unreliable positive indicator for pregnancies.
Then again, it is also true that the amount of blood discharged during implantation somtimes with cramping can be so little that it is hardly noticeable. Many women mistake mistake it for some random bleeding or discharge or staining and therefore, they overlook it. The probability of this occurring is augmented more by the fact that the color of the discharge varies from pink to brown, where the former can be mistaken for vaginal discharge, and the latter for frictional or anal staining. Furthermore, many women (approximately 20 to 30%) experience gradual spotting throughout their pregnancy, thus implantation bleeding may not be distinguishable. Sometimes, some cases have reported that they have misinterpreted the presence of implantation bleeding, to be a result of stress. Thus, the question whether implantation bleeding is good positive indicator for pregnancy remains a topic for debate according to the alternate probabilities and the claims of people.
What is Implantation bleeding, is basically the small amount of bleeding that occurs when an egg is implanted on the wall of the uterus, otherwise known as the endometrial lining. Many women claim that the implantation can actually be felt, in addition to the bleeding, but others contradict the validity of the statement. The period of bleeding can be measured to be around about a week from the day of ovulation. The egg will be fertilized by then and can be called a zygote, which then multiplies in its cellular form to form the blastocyst, which is what embeds itself into the endometrial lining. The embryo then tunnels into the wall of the uterus so as to connect to the circulatory system of the mother. These two processes cause rupture of some blood capillaries which cause the bleeding.
The implantation bleeding occurs approximately five days after the ovum has been fertilized with the sperm. The fertilization takes place in the fallopian tube, from where the zygote travels to the uterus. The amount of blood that is shed is also so little that it takes a considerable amount of time to travel out of the vaginal opening, all this takes about 5 days. If one wants to await the implantation bleeding, a simple undergarment liner will be all that is needed if a woman wants to equip herself.
Now that the question what is implantation bleeding is truly explored, it is important to recognize that this can be a strong indicator for pregnancies if it can be distinguished from all other types of bleeding and discharges. These implantation bleedings are followed by nausea, extreme hunger, appetite loss, constipation, fever, higher than normal body temperature, fatigue, tenderness around the nipples of the breast and abdominal cramps. If a woman experiences all or most of these symptoms, the bleeding can be taken as a positive indication of pregnancy.
