14 wks, first baby. My sis also felt hers move early at 13 wks. The dr's say it's not possible that early, but as soon as the flutters became regular I knew for sure that's what they were! Baby's been moving consistently every day since week 17 or 18.
16 weeks I felt one kick, and didn't feel another one for a week or so. my sister didn't feel anything until like 22 weeks because her placenta was in the way.
