you had your last period on 3 rd April and you are on duphaston
2 tablets daily since may 20 th. Now you are just having brownish spotting for last 4 days.... so I will suggest you to get a urine pregnancy
test with early morning urine sample done.
Duphastone is a hormone- progesterone tablets
. so if your pregnancy test is positive, you can continue with this tablet, after doing a ultrasound
scan as you are having brownish discharge also.
If the test is negative, you can discontinue this tablet so you will get normal periods.
