Iui spotting?

Josey

I am having brown spotting. I am 6dpiui as <a href="https://glowing.com/glow-fertility-program">IUI</a> was 11/17. We did clomid this cycle and the trigger shot on 11/16. I have never had implantation bleeding. Could this be that? Is it too early? Is it just the trigger shot going out of my system? I have been testing out the trigger and it tested completelynegativeas of this morning. Did anyone else have this this early and still become pregnant?
