I know exactly how you feel. I started feeling the baby by week 15 -16 and week 19 it stop for two days. I was so scared! Hubby couldn't calm me down so I went to the Dr to make sure everything was fine, he had a look at baby and listened to its heart beat and all was fine. He said I had felt it very early and got too use to it. It depands on where your plecenta sits and how baby is laying at the time you may not feel a thing. Also as like ourselves, baby has its tired days where it doesn't do too much.

All sounds pretty normal. Take care and keep smiling!!!
