I would definatley ring, there are notices all round my hospital saying if you dont feel movements to ring, and dont rely on your home doppler because it can be a sign of something that a doppler wont pick up, the sign actually tells you not to buy dopplers cause people are relyig on them instead of going to seek medical help, i only rememebr because my husband read it and said no we not buying one of those now. I must admit though when i went in my last pregnancy with not feeling movements they start moving as soon as they ut the belt on you to do teh trace of the heart and movements and midwife said these should be supplied with your notes and if oubt put one on, so i would suggest if you have any pants that are a bit tight round the belly, ( abit not strangling) put them on and see if baby start to kick at it, but definately phone they prefer to see you and nothing be wrong than you sat at home worrying or worse still have a problem tat can be sorted.
