I thought I felt something around 14weeks but then wasnt so sure cause I didnt feel anything again till around 18weeks and then only just a whisper of a tickle. It was only a few weeks later that it turned into proper kicks but then only small in comparison to what I get now!!! People often say they mistake the first few movements for gas but I found it was just that they are so soft and so quick that by the time you go "hey, I think that was it!" it has passed and then you're not so sure anymore.
Before long you will be kept awake but the disco going on in there so that is something to look forward to hehe.
