Wasn't a heavy user to start with. I use mine now maybe once a week. Going of movements now. Seems like whenever I feel him not moving much, he gives me a little kick to say 'here I am'. I think I'll start counting now instead of relying on Doppler. At this stage, I feel it's more important to count and get checked if activity level goes down a lot. I don't want to be misguided and reassured by heartbeat only.
