 [ Symptoms ] i have not have a period for the last 4 months can i still get pregnant [ Disease ] you are seeing the right specialist the orthopedist you could see a different orthopedist for a second opinion if this first one is not solving the problem unfortunately i have no way of determine a cause for your symptoms or have a way of confirming or disputing your current diagnosis blindly over the internet that would take a hands on exam and some imaging studies    obvious not something that can be accomplished on line
