Hi,From last 3 months I am having periods very late, that s why my doctor has prescribed me progyluton for 3 months, and has said that while using this one can get pregnant. But in the description of this tablets it is written that one should not get pregnant while using it. and she has said to start it from tomorrow, which is 20th day of my cycle, where as in the leaflet it is written to start using progyluton from the day 5.Please can any doctor clear my confusions
