Mine started off as bubbles, then more like spasms in my stomach ( only way i can describe it!! U know when your eye or arm twitches?! But from the inside lol?!) finally what I was sure was kicks!! Over s period of about 2 - 4 weeks x
When i first felt it though it felt like when you need to trump but hold it in cos your in a meeting or something and it kind of bubbles and pops inside you!!!
