no periods after taking duphaston

Hi,
Welcome to ehealthforum,
Absence of periods or withdrawal bleeding after Duphaston use can at times suggest possibility of pregnancy (as suggested by other symptoms like altered bleeding).
Urine pregnancy tests (UPT) kits usually start showing positive results after about 20 days post-conception (roughly corresponding to about a week after your missed periods), and hence are not reliable during early pregnancy (some women can keep getting false negative results). The UPT kits are calibrated ones, so unless the hormone levels in urine reach a certain level, they do not show positive results. Blood/serum HCG level estimation is accurate (this can detect pregnancy accurately as early as 11 days post-conception). You can also consider taking a urine pregnancy test (on an early morning first urine sample as it contains the highest concentration of pregnancy hormone HCG) after 7-10 days to see if you get positive results, or get it confirmed by a blood HCG test (avoid lot of fluid intake or caffeinated beverage intake in the previous night before test).
If you suspect chances of pregnancy visit your gynecologist/obstetrician for further examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Look out for development of any other new symptoms suggestive of early pregnancy. Take adequate rest. Drink plenty of water. Maintain healthy diet.
Take care.
