Stitch that won’t dissolve?


Okay so I had my DH look at my lady bits last night because I felt something poking me, turn out it’s one of my stitches that has pushed itself out of my skin!! I’m 3 weeks pp and I’ve heard they should be dissolved by now! Also, my lochia has stopped for the most part but it smells really weird? Is that normal? I know all of this is super gross but thought I’d ask 🤷🏼‍♀️
