Is Big Uterus Size Normal After 7 Months Of Child Birth?

Had a baby 7 mo ago. Seems like my uterine size has not completely shrunk to normal.Is this concerning? Normal vaginal delivery home birth. Some excess bleeding immediately following. After normal post delivery bleeding was over, I would irregularly begin bleeding again sometimes for a couple weeks then stop again. Havent had any bleeding in probably at least 4 months now though.
