My first pregnancy i remember feelings like bubblesfor the first movements and i'm sure i felt them earlier than this and my last pregnancy. I didnt have any bubble feelings for the second nor this one, i am getting just very occassional 'flicks' which could very easily be missed except i know what later kicks feel like. so i dont know if the bubble thing is reserved for first pregnancies! The movements can be affected by where the baby is kicking and where the placenta is. My first pregnancy i loved the feeling , my second almost every movement was sheer torture towards the end , very painful , he would lurch about and parts of my stomach would rise like an island rising out of the oceann! i was like "get this thing out of me!!!" , so it can really vary . Rest assured you will feel regular movements at some point, sooner or later!
