HPT 9 and 10 DPO

I took a trigger shot 12 days ago. At 8 DPIUI you could barely see a second line. The top test here is 9 DPIUI and the bottom is today, 10 DPIUI. It looks to be getting darker. Is it safe to say that this is an actual pregnancy and not still from the trigger shot? Votes and comments are very welcomed!!!
