I've been having a brown watery discharge and a foul smell for a while but thought it was just my period after having my implanon removed. Then last night I removed my tampon before bed and realised there was another string.. I removed a second tampon that looked grey and wrinkly and I have no idea how long it has been in there. I have no symptoms of TSS, just a brown watery discharge like you get at the end of your period. Do I need to anything more or will this discharge just stop?
