Infection after colposcopy given metronidizole, is it working?

I had cold coagulation last week and developed an infection over the weekend.  The GP gave me metronidazole on Monday so this is day 3 and I still have a really foul smelling discharge. I thought it would have got better by now.  Has anyone else had these or any other antibiotics and if so how long did they take to work?  I just want it to go away Frown

I think if you are concerned it's not working then do call your GP - perhaps it will take longer than 2 - 3 days to kick in, but if you are at all concerned, that is what they're there for! xxx
