Many women have knowledge about pregnancy even if they are not pregnant. It is well known that the first sign of pregnancy is amenorrhea, but some women may also experience menstrual periods after pregnancy, which can be very troublesome for many pregnant women. So, is it the first month of pregnancy when menstruation comes?
The first month of pregnancy usually does not have menstruation, but some pregnant women may have a menstrual cycle in the first three months of pregnancy, and there may be a little bleeding every month. If menstruation occurs after pregnancy, it is a bleeding caused by the implantation of the fertilized egg. In the early stages of pregnancy, when the egg is fertilized and implanted, HCG begins to appear in the urine, reaching its peak in the 8th week of pregnancy. The function of this hormone is similar to the reproductive hormone of the corpus luteum, which can promote the development of the ovarian corpus luteum into the pregnancy corpus luteum.
The corpus luteum during pregnancy continues to secrete estrogen and progesterone, which in turn promotes the decidua of the endometrium and ensures the sustained development and growth of the fertilized egg. Generally speaking, bleeding after egg implantation during pregnancy is a physiological response that does not affect the growth and development of the embryo or the health of the mother. So pregnant women don't need to be nervous or receive special treatment.
However, for pregnant women with more bleeding or abdominal pain, pregnancy complications such as threatened miscarriage may occur. Therefore, after being diagnosed with pregnancy and bleeding in a private area, one should promptly go to the hospital for examination to ensure the health of oneself and the fetus.
