Weird pain?

I've been getting a weird pain in my bikini line area on my right leg. I guess that would be my groin area? Usually only when I'm walking or standing. It's like the muscle tenses up really bad and then it goes away. Has anyone else had that feeling? I'm due in two days so I'm not sure if this a type of contraction or is it just a random cramp?
