Calf pain!!!!!

Over the past few days every time I wake up in the morning or from a nap my calf or both calf’s kill, feels like the worst pulled muscle when I walk, it gets a little better as I move around but still slightly sore, not red, warm or swollen just sore. Is this normal?? Should I be concerned about this? Has this happened to anyone else? I’m about 24/25wks along in my pregnancy!
