there is no conditions on getting driver license like this as long as u can manage it safely , its totally depend on u . there is no law or some kind of restrictions that in pregnency u cant go for driving classes , u can apply it now but i bleive u will get chance after 1 or 2 months as mostly training schools give date after 1 or 2 months bcoz of load of so many ppl training already .. better u check with any driving school ...
