Gosh these little bubbas make us worry dont they?

Mine has been very active for the last few weeks, but the last few days she hasnt moved much at all, a few little kicks at night, but Ive noticed the movements are not as strong as they used to be.

I have a doppler at home so I have checked her heart and it is still beating away nicely. Im just a bit worried about the lack of movements. Is she running out of room, or should I be worried?

Thanks for any advice!
