Yo, here I am.
First of all, Dupa, my fine young bro, what's w/ the "stream of consciousness" writing style? Great if you're Faulkner, but hard to read, bro! Use periods.
Anyway, literary references aside, the thing about vaginal bleeding has to do w/ the endometrial lining of the uterus proliferating under the influence of estrogen; nothing to do w/ bleeding in general, or from other organs.
Sounds to me like you had a kidney infection w/ associated bleeding, and you're being treated for that. Is this the impression you got from your doc? Sounds like it's being treated appropriately w/ antibiotics.
I'd wait until off the antibiotics, just so you don't muddy the water, so to speak (don't want to change too many things at once).
If you were only on Sustanon 250mg per week, you may come back on your own pretty quick; depends, I don't think you said how many weeks you were on. Most of the test should be gone after about 4 weeks, which you are coming up on, right?
After antibiotics, you could start post-cycle regimen; I seriously doubt if the onset of bleeding had anything to do w/ the Nolvadex; it was most likely coincidental to the start of your pyelonephritis symptoms.
