If it has been smelling for two weeks, it could be indicative of an infection. I had a miscarriage in Nov. 2004 at 11 weeks, and after they gave me a d&c, I had bleeding on and off, which was intermittently brown and normal -coloured. I let this go on thinking I was just readjusting, but eventually queried it with my doc, who gave me antibiotics. I asked if the infection would stop me from having children in the future, and he said that there was only a 0.6% chance that it would. It could be nothing, but it is always best to speak to your GP. Hope everything turns out ok for you.
