Leg Cramps 😖 relief?

Ma

I’m 17 weeks and have been getting terrible leg cramps while lying down. I got them with my first also, so I know it’s normal, but with this one the pain left over will not go away for anything. When I get up to walk it feels like the muscle is weak and going to give out, and I’ve just been kind of limping around the last few days. I work in nursing so it feels like it’s made it worse since I’m constantly on my feet. Anyone else get them this bad and know of anyway to make it go away? I’ve taken extra vitamins, Tylenol for the pain, and even tried Icy Hot, but nothing is working to make it feel better. I go to my OB in the am, is there anything I can ask for to help it?
