Confusing results, what does this mean???!

Ch
Was testing to make sure HCG Trigger shot was out of system. After a couple strong positives until 3/27 I got a faint BFP, 3/28 BFN digital test, then today (3/30) I got this...could this still b the trigger shot, ectopic b/c I'm only 8 dpiui, or our miracle baby??! All insights are greatly welcomed😊
