soya isoflavones

Has anyone here got any success stories of using soy when ttc? I have started this cycle as my last 2 cycles I haven't ovulated and my periods have been irregular for 8 months. I started cd 5 so will take them to cd9. Im not sure if it's a coincidence or not but the last 2 cycles  of opks the test line has either been so faint it's barely visible or no line at all. I just tested an hour ago and although it wasn't a positive yet, I had a clearly visible line! I have no idea if it's down the soy or not but I have my fingers crossed 🤞  I get a positive 
Opk this month.
