Pregnant or trigger?

Summer

I had an IUI on 7/3. I did a trigger shot on 7/2. On 7/8, my RE had me do a booster trigger. The first shot was 2/3 a dose and the second was 1/3. Today, I am getting pretty positive tests. Does this seem like it could still be the booster trigger? I don’t think it would be in my system still.
