Anyone..? 😬

I am currently 12dpiui, the trigger was out my system at 8/9dpt, I've tested the last couple days, stupidly I know, and had BFNs 😕 but also yesterday and today I've had brown discharge, I feel I had this last time around also but I really cannot remember. I've had cramps, stabbing/shooting pains and alot of niggles for the past couple of days also. It's so so hard not to symptom spot and just forget what's going on 🙄 has anyone had brown spotting or anything before a BFP, am I out as I'm 12dpiui? I've actually started thinking about IVF recently I'm that sure I'm going to be out..
