18 + 2 still no movement?

Jessica
This is my first pregnancy. I have felt SOME movement, but not much. And it's been about a week since I felt anything. Has me wondering if there's something wrong with the baby or if I'm just still early and won't feel anything for a little longer. I don't know the placement of my placenta, but will definitely be asking at my next appointment? When did all you lovely ladies feel movement?
