Anyone else randomly wake up feeling like they got hit by a truck?

So yesterday I stayed home with my kids, didn’t really do anything. Now this morning my whole body aches and is really sore. I also feel a slight headache. I don’t have any other symptoms so I don’t think it’s the flu. It’s just so strange to feel this yucky like I’m recovering from a hard workout when I did nothing the day before. I checked my bp and it’s normal too. Any thoughts? I’m 30 weeks today.
