Tubal after csection.

My doctor offered to give me a tubal after my csection. I am due in July and my husband and I are done having kids. He has already offered to get a vasectomy. But, I was thinking since I am already there that it might just be a better idea for me to get my tubes tied. I am worried about the side affects after the surgery. I am worried about hormone differences and the possible risk of it increasing the risk of postpartum depression. Are these things to be worried about?
