Hi,
Thanks for the query.
Duramine contains phenteramine.
Half life of phenteramine is around 25 hours.
So, after stopping the drug by this time the drug might have cleared from circulation.
But as there is around 20 kgs
weight loss in your case, that may have some impact on menstrual cycle.
And it may take some time for regularization of the
hormonal levels.
So, better to wait for one to two months.
Possibly by that time, your cycles will get regularized.
Then you can track the ovulation in next cycles and plan intercourse around that period.
This will increase the possibility of
pregnancy.

Take care.
