Thanks for the query.
Delay in periods can occur due to many causes. Susten
also can delay the menstrual period.
And it is early to comment about pregnancy
So you wait for one more week, possibly by that time you will get periods.
Urine pregnancy test kit may not detect pregnancy this much early.
If you do not get periods even after one week, then go for pregnancy test.
Continue talking susten and also start taking folic acid
