Stitch hasn't dissolved 2 weeks post-op?

Hey friends! As title says, i have a stitch that hasn't dissolved yet and it's been 2 weeks. My other incisions look great and no stitches visible anymore but this one isn't looking as good. I have no clue if it's normal for this to occur, but seeing as my other stitches are completely gone and incisions are looking good, I'm getting a feeling it may not be. I'm unable to attach a photo at the moment. Has anyone else experienced this? Or would it be best to just get in touch with drs? My post op appointment isn't til late April :/
