I'm quite worried - for the last few weeks I have been feeling quite a bit of movement and maybe even a few gentle kicks. All day today I haven't felt a thing so I came home from work and got the doppler out......it took me about 20 mins to find a heartbeat and when I did it wasn't the usual loud noise. I've just put a new battery in too! I thought I'd be getting movement all the time now, and am just a bit worried.....do you think it's normal?
