Less moments

Im 32+2 and lately all of a sudden I haven't been feeling baby much at all. It's starting to worry me and I don't know if I should go in. I felt him really low the past 2 days but not as active as he has been and again it was a lot lower than normal. It was like he was in my vagina. Today I haven't felt him at all. This is not normal. Has something like this happened to anyone else? Advice on what to do?
