Trigger shot or start of BFP?

I had trigger shot 12 days ago and

IUI

10 days ago. I feel like I see a shadow today, but I guess it could still be trigger...? Last test was 9dpt/7dpiui, and trigger was visible but really faint then. Thoughts on whether today’s shadow is still trigger shot or if it might be start of BFP? I know there’s no way to know other than wait and test again...this is just for funsies. Top test is from Wednesday FMU; bottom is this morning SMU (didn’t drink anything).
