Trigger shot + HPT

So we did a round of some meds then did the trigger shot (Ovridel) on 3.1, so ovulated 3.3. BD 3x in 36 hours after taking the shot. Took a preg test yesterday and today and both were positive! So as of today I'm 15 days past trigger and 13 DPO. Think it could still be the shot in my system or is it the real deal? I've read the shot should be out between days 10-14 but I'm not sure! Thoughts?!
