In some cases of early pregnancy, the amount of progesterone produced by the corpus luteum is too low to cause a complete stop of menstruation.Then, there will be the normal menstrual bleeding period, except that it will be more scarce and will take less time Often, unlike the previous, is painless. This partial stopping of menstruation is often an additional factor impeding the statement of pregnancy or determine the date of fertilization, and also calculate the date of birth. Rarely, but it happens that after the expiry date of the next cycle bleeding occurs again, except that it will be even more faint than the previous. In rare cases, the woman “menstruate” for the entire pregnancy. Although this thephenomenon is not fully understood, it is known that it remains without affecting the normal development of the fetus.
