Thanks for your query,
Duphastan is a progesterone. Progesterone is given for luteal phase support for progesterone deficiency
in the second half of the cycle.It does not increases the chance of pregnancy
, but it helps in sustaining the pregnancy after it occurs in patients with luteal phase defect or in patients with unexplained infertility
. So it may be helpful in some cases .
Periods will start after stopping duphastan. Dont be disheartened, even in a absolutely normal couple, chances of pregnancy per cycle is only 25%.
Best of luck..
