I am 18 + 2 and am yet to feel any movement, this is my first pregnancy and I am aware I might not feel anything until nearer 20 weeks but I am still paranoid ! I am also a bit fatter than I would like to be and wondered if this makes any difference to feeling movement ? we heard the heartbeat at 16 weeks and was told it was good and string bt I am worrying something has gone wrong inbetween.
