When will I heal from child birth?

Dear Doctor, I had my second baby six weeks ago, naturally. I ripped really badly and had to be stitched. However, the bleeding comes and goes, and sometimes is really heavy. The stitches haven’t fully healed either and it’s beginning to worry me because when I had my first child three years ago, both the bleeding and the stitches were fine by this point.
