BFP or still the trigger shot? —- Update: BFP!!

Hey everyone! So today is day 14 since my trigger shot (Pregnyl, 10,000 units). I didn’t test out the shot at all because I didn’t want to drive myself crazy. Like an idiot, though, I got antsy and just did a test this evening. Could this be a BFP or is it most likely still the trigger shot? My period is due anytime between now and Friday so I’m not really that excited because I’m assuming it’s the trigger. Just figured I’d see what others thought. 😊

Update: It was a BFP!! I had bloodwork done today to confirm it—16 days post trigger and 14 days post IUI. With 3 previous losses under my belt, I’m nervously ecstatic! 🙃🌈
