Question

why periods are miss during pragnancy?​

Answer 1

Answer:

The menstrual cycle is the shedding of the uterine lining that would otherwise have housed a growing embryo in pregnancy. When a woman becomes pregnant, that uterine lining is necessary to house the new embryo and is retained inside the womb. Since the lining doesn't shed, the woman doesn't menstruate during her pregnancy.
