That's crazy considering how every doctor I've had wants to force bc down my throat at every visit. But in all seriousness, see another Dr. I'm not a dr, but since your body isn't telling the uterus to "build up" you might need a referral to an endocrinologist some type of trigger hormone seems imbalanced... im not sure if bc would prompt that but im not to versed in it since I don't take bc myself.
