Swollen feet

Is there a point where feet can be "too swollen"? I'm almost 37 weeks and my feet have gotten SO swollen to the point where there's a crease above my feet, it's hard to bend my toes and hard to walk. And they're kind of blotchy as if it's cutting off the circulation, im not sure. Is this just normal for the end or is it dangerous?? Going to the doctor tomorrow, but figured I would see if anyone else is going through the same thing
