How long is trigger shot in system? Bfp 3dp5dt

We did our first

frozen transfer on Tuesday. I couldn’t help myself and tested today at 3dp5dt. We only had one 6 day frozen embryo. It’s pretty early but there’s clearly a positive line... could this still be from the trigger shot I took 10 days ago? Don’t want to get too excited yet.

UPDATE: pregnant!!!!!
