baby moving less? advice?

Anyone else's May baby moving less these days? It's come all of a sudden that my baby doesn't seem to be moving as much as he use to! I still feel him and sometimes I shake my belly just to get him to move so that I know he's okay. I read it's normal near the end as they have less room to move? I think he may have moved too because my belly looks like it's dropped? I'm 34 weeks tomorrow
