why did I do this to myself? 2 days past 3 day transfer

I decided to test out my trigger because Im a poas addict lol. Told myself one every fmu untill  trigger is gone. I am 7 days past trigger. This morning it was barely there. Hold it 10 different ways and squint barely there. Out of boredom    I just decided to take another thinking it would be completely neg. nope. Darker. Way to soon. Nurse called me this morning. In the convo she said today or tmrw was probably implantation day and that a home test may pick up hcg in a few days. What the.......?
