Pia is pregnant now, i think they just show the extreme in serials, whenever the girl had unwanted intimacy she got pregnant, Pia & same happened to Shubhra, i mean getting pregnant in life is just not that simple.
while, on the other hand, there r other extreme cases, like Tara when she wanted the child she couldn't get one, when Kaveri planned to become a mother she had to buy (i really hate to use this word here for a child) a child. can't they show some normal routines about pregnancy?
