Decreased fetal movement at 40+2?

Some things I've read say it's normal for baby to not move as much at the end of pregnancy. Other things say it isn't, I'm a first time mom so I don't really know too much of anything about what's really normal and what isn't but he hasn't moved much since about 7-8 last night and I've been getting about 10 Braxton hicks in an hour...I'm not sure if I should go in or what
