Pelvic Pain But Natural Birth

Any mums here had severe pelvic pain but managed to give birth naturally? Does not matter with or without epidural/laughing gas. I've never experienced or had pelvic pain with my other pregnancies. My gynae says it's normal because of baby's weight. And I also read that it's normal for those who have been pregnant before. Having quite the difficulty to walk, stand for too long especially when I need to cook or even lift a leg up to wear pants. Turning in bed can also be quite painful. Sigh!
