Physiological causes of bleeding during pregnancy do not pose a threat to the health and life of the mother and fetus. Therefore, no treatment is required. As a rule, a woman notices such discharge in the first month, less often in the second and third. They differ from regular periods in volume, intensity, and duration.
Bleeding in the early stages may occur for the following reasons:
• as a result of implantation of a fertilized egg;
• if conception occurred towards the end of the cycle;
• with false menstruation, or pseudo menstruation;
• when two eggs mature at the same time.
When the zygote attaches to the wall of the uterus, small blood vessels are damaged and a few drops of blood may be released. This is called implantation bleeding. But such discharge is very scanty and lasts no more than 1-2 days. Additional symptoms may include mild pain in the lower abdomen and general malaise. For most women, the process of egg implantation goes unnoticed.
When conception occurs towards the end of the cycle, the body does not have time to adapt to maintaining the pregnancy. In this case, bloody discharge similar to menstruation is possible. The situation is typical for the first month. Next month, as a rule, this does not happen.
The situation with false menstruation is more mysterious. This happens in very rare cases. During pregnancy, a woman has full menstruation for up to 3-4 months. Medicine is unable to explain such unique moments.
The simultaneous maturation of two eggs is also quite rare. In this case, one cell is fertilized, and the other comes out along with the blood. Such “menstruation” is typical for the first month; in the next month, there is usually no discharge.
