Am I crazy?

Okay so I've had this cough go on for about a week now after I had a bad acute flu thing and after a bit I noticed my pelvis (specifically my vaginal muscle) hurts when I cough? Now it's gotten to the point where if I cough it feels like it's pulling and it hurts and when I lift heavy objects it hurts and I hate knowing it's gonna hurt when I cough. Did I pull something?
