4 days post fresh transfer

I did my very first fresh embryo transfer on Monday (5 days ago) and yesterday which was 4 days post transfer I did a test and a faint positive was there. Could this be real?! I did do a ovidrel trigger shot but only half the dose as I’m on low dose hormones so surely that would be out of my system by now? Trigger was 12 days ago when I did the test
