Movement Almost 34 Weeks

So, I'm 33 weeks & 5 days.. over the last 24hrs my little guy has slowed waaaaay down. I'm talking, I rarely feel him anymore. Maybe slightly shift every couple of hours. He used to kick & punch me so strongly that I'd have to catch my breath. This isn't like him. Do they normally slow down movement wise during the last few weeks of pregnancy? FTM, having a freak out.
