Woke up from nap haven’t felt baby

I took a nap from roughly 12:30 to 3, and I don’t think I’ve felt him since I’ve been up. Since lunch time, really. Been in the car for the last 50 minutes and won’t be home to lay down/drink some OJ to see if he moves for at least 2 or 3 hours. Should I worry? 27 weeks 4 days
