What happens to the ovum, menstruation and ovulation after the fertilization of the ovum?

Answer

After fertilization:
(i) Ovum forms zygote which fixes itself into the wall of uterus and starts to develop as an embryo. The embryo tissues and mother’s uterus wall tissue form placenta which is the vital connection between foetus and the mother.
(ii) Menstruation and ovulation do not take place during pregnancy. However, they are resumed after the birth of the child.
