Excruciating pain in both calves

Ok so Monday morning I woke up to what seemed to be Charley horses in both my calves. I was crying the pain was so bad. It went away quickly though. But since then walking has hurt pretty bad. Today seems worse than yesterday when I walk. I am not sure what's going on. I thought maybe Sunday I over did it with walking but I think the pain would lessen instead of get worse. I can barely walk. But I don't know if I should call my ob or just ride it out.
