Any of you BFP ladies have achy legs early on??

I am 9 dpo and for the past couple nights my legs have been soooo achy for no reason. It reminds me of growing pains or how I felt after pulling a double shift as a server lol. Haven't done anything to cause it though so thought I'd see if anyone had ever experienced it and been pregnant!
