swollen legs and feet

Hailey

So, I'm 34 weeks pregnant. The last few days, my feet and legs have swelled up. However, my left leg and foot is a lot more swollen than my right and it's really sore. Like, I limp when I walk. I've also been having THE WORST leg cramps when I lay down to go to bed. Is this normal? I've always been told swelling in your hands and feet is normal, but I don't think I should be in pain and unable to sleep due to the cramps.
