Thanks for your query.
GESTOFIT 300 is a progesterone
tablet which induces secretory changes in the endometrium, promotes mammary gland
development, relaxes uterus, blocks follicular maturation and ovulation, and maintains pregnancy
As egg is already released then it will prevent proliferative changes and promote secretory changes so that implantation
can occur and will help to maintain pregnancy.
Hope i have answered you.
