Perineal stitch?

J

I’m 6w postpartum. I had quite a few stitches that i was told were dissolvable. I haven’t seen any until when I wiped after the bathroom until just now.

I had my 6 week postpartum check up earlier today and the midwife said all my stitches were healed, but then I got this when I wiped.

Is this a leftover stitch?
