Hi Tracy,
My nurse told me that it can take 3 months for the insisions to fully heal and that during this time even white fluff will work its way out!?! Did you have dissolvable stitches? Sometimes there are stitch knots on the inside, so it may be them just working their way out as part of your healing.
Maybe just send your nurse a pic for peace of mind, but I’m sure they’ll be okay. Xx
