Hey hun pop a plaster over it, it looks like your spitting a stictch it wont reopen but best to keep covered, i spat most of my stitches on the one side and it opened up completly but this was about 2 weeks post op so everything wasnt healed like you are now at six weeks just keep an eye on it its nothing to worry about as the skin looks healthy no nasty colouring or anything, the nurses usually let you know that this can happen especially at the end which the body always seems to struggle to heal apparently but babe dont worry xxx
