Is your placenta at the front? This may be why your not feeling many movements x
I know it is hard but try not to panic. If they say there isn’t nothing to worry about then believe them. They know what they are doing and you are in the right place. Babies change position all the time and the bigger they get the less they can move x
Eat something sugary and drink a fizzy drink, try and relax and wait for more movements Somedays my girly has more chill days/hours than others and it is quite an anxious time
