Swelling and numbness

I’m 32 weeks pregnant and last night my calf to my toes started hurting a lot. I couldn’t sleep through half the night because when I laid on my left side it would make the pain 3x time worse and have a numb and swollen feeling to it. I woke up this morning and couldn’t walk on it. It feels like it’s swollen and numb but doesn’t look like it and is in constant pain nothing like a Charlie horse or anything. Now the numbness have move the the left side of my leg down to my toes but the pain is going in and out. Has anyone else every experienced this or something like it?
