Testing out trigger

Haley

I took a test last night (7dpiui & 9dpt) to see if the trigger was still in my system and it was negative. Does that mean the trigger hormones are gone? Sorry I’m new to this.. does that mean the <a href="https://glowing.com/glow-fertility-program">IUI</a> failed? Or could there possibly not be enough HCG to defect on an at home test if I was pregnant?
