Duphaston is a brand of synthetic hormone (dydrogesterone
) that is similar to the naturally occurring female steroid hormone
progesterone. Progesterone plays an important role in regular menstruation
, the development of a healthy uterine lining and maintaining pregnancy.Hormonal changes due to Duphaston use can result in acne, breast tenderness or enlargement, changes in sex drive, fluid retention, spotting between periods
and weight gain.Since you have missed the period only by a day you cannot definitely say that you are pregnant.You may wait for a week of the missed period and then do an urine pregnancy test to confirm pregnancy.
