Poetry / Baby Doll, Phenomenal Woman - Comparing and contrasting two poems [3]

I have an essay due in two days too on either contrasting or comparing two poems that I have chosen from our literature book. One is by Piercy, title Baby Doll and the other is by Angelou, Phenomenal Woman. What the two have in similarity is about the images and symbolism of womanhood. However how they contrast is that one woman believes in herself and the other doesn't. I am very new at this. I need any help available. Thank you very much.
