Muscle pains in legs 23 weeks pregnant

Garcia❤️🌱
So I'm having horrible leg and butt muscle pains. I noticed my stomach has gotten a little bigger but this morning I woke up with horrible muscle pain! It feels like I did 100 squats and ran 3 miles! Is this normal, what causes this?  It's getting to the point where it's hard to get out of bed. I looked it up on google and no luck.
