HCG trigger 5000 units- how long?

neener*neener*

Hi Ladies!

 This is my first medicated cycle. How long did it take the 5000 hcg trigger shot to be out of your system? I've been trying to test it out using internet cheapies to see how quickly I metabolize it (for future reference if needed).

I'm 6 dpo 7 days past trigger. I still had a faint line this afternoon.
