baby movement

So I've felt my son move today, but not for about 4-5 hours now. My doctor said justfeel 10 movements a day but I didn't really count and it's unusual that he hasn't moved in so long. I called the after hours number for my doctor but they're taking forever to call me back, should I just go in without waiting on an answer from the doctor? I'm getting nervous. I'm 35+4
