Unfortunately no clear answer. It's all over the map depending on dosage and metabolism. Some seem to have it out really quickly, others it takes 10-14 days. I've also found for me, it varies every cycle. Just keep testing to see if it gets darker.

8DPIUI seems ridiculously early to have a legit +, I would definitely think anything at that point was trigger related. I would wait a couple more days (at least 2 more days) and see what that result is. FWIW my triggers take forever to fully leave my system at least 12-13 days, but like sailor mentioned, everyone is different.
Good luck.

Usually my trigger is out by 10 days past. I think the rule of thumb is one day for every 1,000 units of HCG, but like everyone above says, it varies. Mine seems to be sticking around longer than usual this time.
Good luck!
