Implantation bleeding is the phenomenon that occurs when the blastocyst embeds itself in the uterine walls of a person. It burrows deep into the uterine wall, which has prepared itself by building a mesh of crisscrossing capillaries. The bleeding occurs when the process of attachment of the embryo to the uterine walls causes the rupture of many of these capillaries.
The bleeding will usually be in the form of a smear or a stain on a woman’s undergarments. The color can be anywhere from a pinkish color to a brownish one. Pink or red smears will usually be more in quantity than brown stains. This is because the color of the bleeding depends upon the time required for the blood to reach the vaginal opening or the cervical opening. If the time elapsed is longer, then the color of the stain will be generally darker.
Many mistake this bleeding to be their regular menstruation, while many others conjure up worse scenarios related to miscarriage. Other possibilities with the implantation bleeding can be related to stress, random discharge related to vaginal infections, friction or anal outflows.
A good indicator that could be used to differentiate between the bleeding related to miscarriage, and regular cramps with implantation bleeding associated with the latter. The cramps can even occur without an occurrence of bleeding. These cramps are caused during the second stage of the attachment of the blastocyte to the uterine wall. The first stage is where the blastocyte reaches the wall of the uterus, and the second is where it undergoes the process of embedding itself within the uterine wall. The second stage cause muscles of the womb to contract as the blastocyte burrows through.
The intensity of the cramps also distinguishes them from those related to miscarriage. The cramps are usually mild to moderate in intensity. These cramps with implantation bleeding are in fact no different from the regular cramps of the abdomen that women face during their menstruation. The duration of these cramps last for twenty four hours, but in exceptional cases can stretch up to forty eight hours. On the other hand, in case of a threatened miscarriage, the patient will undergo moderate to severe cramping of the abdomen that can stretch for more than forty eight hours.
Except the cramps with implantation bleeding, other factors that can be used to differentiate between the bleeding that occurs during implantation and other sorts of bleeding, is the quantity of blood discharged. The quantity of blood, in accordance with the intensity of the cramps, will be insignificant in amount. It is far too less than the normal flow of regular menstruation, and far too little to be the discharge caused during a threatened miscarriage. This bleeding is also negligible in its effect on the blastocyte or embryo.
While many deny the existence of any such phenomenon, one can always take advantage of the benefit of doubt. This is because, for many who can interpret signs correctly, this can be utilized as a positive indicator for pregnancy.
