I'm Just over 16 weeks and I'm trying to work out if I've started to feel the first flutter?

Lowri • Married July 26th 2014 ? Expecting baby number 1 on 29th August 2015
Some times I get a little bit sicky feeling and feel something in the pit of my stomach it's my first baby so I'm not sure...
Wondering when everybody felt their baby first move?
Thanks Ladies x
