In early stages of pregnancy (1-2 weeks) the majority of future moms do not experience any subjective pregnancy symptoms. Very seldom patients report feelings of discomfort, pricking and slight abdominal cramps. The symptoms may be accompanied by slight bloody discharge in the form of pink, light-brown or reddish spots on the underwear, unpleasant aftertaste and mood swings. Most often patients pay no attention to such symptoms. Once the fact of pregnancy is being ascertained, woman confirm, that they had previously experienced not very discernable symptoms, which are most often associated with the so-called implantation.
What does the implantation process assume?
One week after implantation, human embryo has the form of microscopic bubble, which is called blastocyst. From now on the fetus needs nutritive substances from the external environment in order to continue growing. Penetrating into the uterine wall, the embryo may receive all the necessary nutrition from mother’s tissues and blood. The adhesion process and further invasion of the blastocyst into the endometrial lining is commonly referred to as implantation. It takes place by means of the ferments, produced by the fetus. They “fret” the uterine mucous lining, allowing the embryo to delve into its thickness. Implantation is rather a quick process. In 24 hours the blastocyst invades the mucous lining to its ½ and in 40 hours it invades endometrium completely. The affected area over the implanted fetus heals over in just 4-5 days. From this point the future human being is supplied with all the necessary substances exclusively by means of the mother’s organism.
Implantation is a critical point in pregnancy: the affection factors threaten to kill the embryo.
