dissolving stitches?

Hi ladies, I'm 17 days postpartum and my doctor after my vaginal delivery said the stitches I had for my second degree tear and two grazes would dissolve within 10 days. Well, when I look down there with a mirror I can't see any of the white stitches anymore, but I can definitely feel them under the skin of my second degree tear. Any idea how much longer I should wait for them to dissolve? And also, I swear the doctor stitched my tear up too far, I can't see the opening of my vagina anymore! What the heck!! Is that normal for them to stitch up a bit too far?
