Unfortunately, even such an obvious seems to be the signal is not 100% sure, because sometimes you can hear that somewhere lived a woman who had pregnant "normal periods".
Fairy tales? Yes and no. It turns out that when you are pregnant, you may have bleeding, which is not considered to be menstruation, but is often mistaken for it. Consequently, a woman who thinks she has menstruation is actually pregnant. This can be clearly confirmed after a pregnancy test, and 100% after a visit to the doctor.
Pregnancy and period
We do not have periods in pregnancy, they cannot occur during 9 months, when we expect the birth of a child. It is impossible.
Because menstruation is the peeling of the uterine membranes, and this process has one purpose - to prepare the body for a new life that is not in it. Not without a reason menstruation is a signal of no pregnancy.
Menstruation cleanses the body and prepares the woman's body for conception. If fertilization has already taken place, it is not needed for anything. It naturally disappears and therefore the period of pregnancy is not possible.
Scarce period and pregnancy
Bleeding during pregnancy does not mean menstruation. Exfoliation of the womb when we are expecting a baby would prevent the fetus from developing further. Therefore, bleeding, which can be confused with menstruation, has a completely different source to it and it is worth realizing it clearly. It is usually less abundant than menstruation, often in the form of bloody discharge.
The first bleeding usually occurs when the embryo is implanted. They can usually be seen about 6-12 days after conception. The process of implanting an egg in the wall of the uterus occurs 5-7 days after fertilization. Bleeding during implantation usually occurs when the embryo hits the blood vessel in the womb wall and damages it.
The walls of the uterus are very well supplied with blood during this period and therefore there may be a slight spotting. However, it does not resemble the classical period in any way - the spotting is slight, often it can be hardly noticeable.
Minor bleeding may occur again on the day on which menstruation would normally occur. However, it is not as intense, the blood also has a different color, so it is easy to see that it is "unusual". Such bleeding in pregnancy is usually a sign of hormonal changes. Sometimes it is a signal from the tired body of the future mother that she slow down, because her body cannot keep up with the changes that occur in herself.
Bleeding during pregnancy, regardless of the abundance and time of occurrence, should be consulted with a doctor. It may be a disturbing signal that will require intervention.
