The pain can be normal. It can be from the cyst formed on your ovary to help support the pregnancy in the beginning or from your ligaments stretching. But if its intense pain or unbearable it may not be normal. You should call your doc in that case, or if you just need some reassurance. But it should be normal if its just an ache or a slight twinge here and there. Good luck and keep us posted! And congrats on the pregnancy!
