Baby doesnt move

I am 23w5days .. I read somewhere you should feel ur baby moving like atleast 8-10times atleast in an hour.. But i dont feel my baby moving for whole day mostly.. Maybe it moves but i dont feel anything.. I only feel him during night time but still not that much.. I asked my doctor but she said he is fine and everything is normal.. I really wanna feel my baby move.. Please tell me is this happens with someone else too? Or what should i do about it
