Okay mommies I need help, so I am currently 19 weeks and 5 days pregnant. Every time I lay in my bed and my left leg get a horrible cramp that makes me not able to move my leg without it hurting. It feels like my leg was twisted from the top and walking feels horrible until I walk about 30 steps how can I help with this cramp. I only get it when I lay on my bed, I have it about 2 or 3 feet tall could it be the height or just might need a new bed, over the week I was on a air bed and didn't feel this pain until now again.
