No after 21weeks placenta won't migrate, and this is grade 3placenta previa,. It is said that grade 3placenta previa means you are sitting on volcano, where any time bleeding can start, you are blessed if no bleeding, so give thanks to GOD. Your HB should be 13,so if any time bleeding will start your life can be safe, you should avoid sex, and don't hold urine, and avoid straining during passing motion. Ok
