I'm 16w + 4 and over the last couple of days have started to feel some flutters and pops which I think is the baby making itself known 
It's gotten more obvious over the last couple of hours but it's always in the same place, on the right hand side. Is this normal? Shouldn't the baby be moving around all over the place? Or should I be worried (or do you think maybe it's not the baby at all?)
