Possible infection after LLETZ

I’m 15 days post LLETZ procedure and have been having the common light brown, bloody watery discharge with unpleasant odour. Some have described it as vegetable water smell or metallic. I don’t know what vegetable water smells like, but it’s not metallic. The black flecks seem to have come to an end, but i also seem to have some kind of uti infection. Has this hapened to anyone else? I’m wondering if this smell and the coloured discharge is coming from a uti infection or the lletz. I’m so anti antibiotics and want to avoid them at all costs but I am fed up with all of this now. Any feedback would be greatly appreciated.
