hey babe-
the earliest movements can be at about 15 weeks. but thats rare. its usually in girls who were very small to begin with or in subsequent pregnancies. most feel it sometime after the 18th week. the latest is about 25 or 26 weeks.
Theres a great site that you can use to calculate about when you should feel the baby and it fantastic for everything else! just put in your last period date and click on all the little things you want to know!! (of course teh movement prediction and such isnt always right but its the average time)
