I diddn't even feel DD until 24ish weeks... This time I havfelt movements from around 19 weeks.

Each baby is different, and some days the way it's positioned you may not feel much as there is more room that wayl...

Don't stress too much, if you are a bit worried, have a very icy cold glass of OJ and lay on your back for 10 mins or so, you should feel some kicks then... but remember that some times it will be a slight kick and others you'll feel like your tummy will burst open from the force of the kick...

Good Luck
