Haven't felt them move???

Mandy
I'm 17 weeks 2 days and still can not feel my little girls move!  How far along were you when you first felt your babies?  My dr was asking at my last appt if I have felt them at 15 weeks.  And my belly seems to be bigger on one side than the other this morning when I woke up and is still that way 4 hours later!!  Alls good or be worried?
