Hi doc...i just had my tvs...the tvs showed that theres no mature egg in my ovary after my period from may 13 to 16..d doc said my fertile week is this week may 23 to 27..she prescribed 8 tablets duphaston to be taken on may 31 to june 3...i was confused because my ob prescribed 8 tablets.why 8 tablets it should be 4 tablets because it is to be taken once a day on may 31 to june 3?
