I've had a similar issue over the past week. Movements have appeared to be less, and definitely less forceful. I had the midwife on Thursday and I'm measuring slightly small, so wants to see me again sooner than scheduled, but has also told me to keep an extra eye on movements so I'm now more paranoid! Since yesterday evening it's moved loads though, so I think it may have just changed position to something less obvious to feel, but I'm going in later on to get checked over anyway. I suffer with anxiety and I can see myself being a weekly visitor until this baby comes....but who cares, I'd never be able to live with myself if I just assumed everything would be ok then something terrible happened. I've been told to never use a doppler as this isn't an indicator alone that everything is indeed ok, so I would always go in on the safe side.
