Stitches coming out from perineal tear at 6 days pp

St

I have been having bad burning where I tore so I grabbed a mirror and took a look and it looks like my stitches came undone. They haven’t fallen out but there are just strings hanging. They are not in a knot or anything. There is also a little area that is slightly open. I called my doctor but cannot see her until next week. Wondering if this has happened to anyone and how was it treated?
