The start of the pregnancy process; The egg, a female germ cell, is the result of fertilization with sperm, a male germ cell. The ovulation cycle after fertilization stops completely, except for very rare exceptions until the postpartum period. Therefore, menstrual bleeding does not occur during pregnancy.
The condition, which is called vision among the public and mixed with menstrual bleeding, is the bleeding caused by the damage the fertilized embryo causes to the wall of the uterus when settling into the uterus.
This event is called implantation or settlement bleeding in medical language. Settlement bleeding occurs in an average of 25% of all pregnancies.
Why Menstrual Cycles Don’t Happen during Pregnancy?
Many changes that women do not experience in other stages of their lives occur during pregnancy. Some of these are obvious changes in the type to be noticed from the outside, while others are changes in the body.
Menstruation: In order for the pregnancy to occur and the baby to develop, the uterus must be in a continuous cycle. For possible pregnancy preparation, the uterus has various hormones and we have a sequence of changes in the average of 28 days 1 occurs. When fertilization does not occur after this preparation, the uterus throws out failed preparations to prepare itself for the next cycle.
For this reason, blood thrown out with menstrual bleeding; The removal of the structure, which forms the thickness of the uterine wall, is the egg cells that have expired and blood clots that occur as a result of other structural changes.
In the first stage of the menstrual cycle called the follicular phase, the rate of follicle stimulant hormone levels increases in the blood as the layer of the uterine wall begins to thicken. In other words, the uterus is ready to fertilize the egg cell, which is drafted with the help of a hormone, while thickening the uterine wall so that the baby can hold on as a result of possible fertilization.
Contrary to what is known, the uterus does not mature a single egg cell every month. A series of sketches of ovaries ensure that egg cells do not grow, while the body begins to produce estrogen after one of them grows faster and stronger than others. With this estrogen production, all other maturation egg cells are prevented from being disintegrated and fertilized.
Menstruation occurs as follows: in case of fertilization of the egg, the hormone called HCG or pregnancy hormone begins to be produced. Then the body begins to produce progesterone to feed the developing fetus and keep bacteria away from the uterus.
The hormone Progesterone takes on a protective task of preserving the uterine membrane and the thickness of the mucus in the uterine tract. When progesterone performs these tasks, it protects the uterine structure without deterioration during pregnancy and menstrual bleeding does not occur.
Why Does A Settlement Bleed So Called Vision On It?
Embryo; it is connected to the place in the womb where it considers it suitable for itself in order to grow, thrive and meet all vital needs with the realization of fertilization.
At this stage, if the baby’s place is in a section containing a large capillary vessel, it is possible that some bleeding will occur here. This condition, popularly known as vision, is actually a case of settling or implantation bleeding.
Settling bleeding is invisible in every pregnancy and is not seen is a problem. In short, the settling bleeding is completely associated with where the baby is clinging.
When the egg cell is fertilized with a sperm cell, the cell that will make the baby occur relate to the uterus must have a specific cell divide.
In short, even if the pregnancy occurs, it is necessary to wait for the baby to hold on to the uterus. This time usually occurs in days of menstrual delay. Another reason why settlement bleeding is called ‘sight on top’ during pregnancy is due to this.
Differences Between Menstruation and Settlement Bleeding
• While the settlement bleeding has a small amount and a short-term effect, menstrual bleeding occurs more intensely and longer.
• Although it may coincide with the same period as fertilization time, settlement bleeding usually occurs 1-2 days before the expected menstrual period.
• While menstrual bleeding is mostly vivid red, settling bleeding may be closer to pink.
• Unlike menstrual bleeding, bleeding and discharge caused by settling into the uterus usually do not last more than 48 hours. Many women experience only a few hours of staining, a spot or a current trail.
• While menstrual bleeding is painful for most women, settling bleeding does not cause cramping and pain except for rare exceptions.
Other Causes of Bleeding during Pregnancy
Bleeding other than implantation bleeding; Infections in the first weeks can occur as a result of conditions such as ectopic pregnancy, false pregnancy, myomas and mol pregnancy that exist in the uterus.
It’s the 20th day of pregnancy. bleeding up to weeks may also be directly related to miscarriage. Bleeding during the last trimester period of pregnancy can occur due to the decrease of the blockage that protects the uterus from germs, premature separation of the placenta, risk of premature birth, placenta anomalies.
Since no bleeding is considered normal during pregnancy, you may need to be in frequent contact with your doctor.
