Third Trimester Symptom?

Catelin • Mommy to be in October 👻🍼
so I woke up this morning feeling like I got hit by a truck.... literally me legs, back, arms, everything is SUPER sore. I haven't done anything stressful or strain full. no lifting or anything of that sort that could even make me sore. I'm not sure what's causing it. anyone else have the same issue or anything similar? also, I'm 37 weeks. please comment, anything helps! thank you ladies
