I'm currently 21 + 4 and as yet I've not felt any movements or kicks from my baby. This is my second and with my ds I'm sure I was regularly feeling him from around 18wks. I know that this time the placenta is all in the front so maybe that?s affecting things as well. When I was scanned at 19 weeks all was ok and bb was moving well so. Anyway should I be concerned at lack of movement and when should I feel something?
