Trigger or BFP?

Ruthie • 40 years oldTTC for five years. 2 ectopic pregnancies and one miscarriage. One IVF and failed. 😥 Here to just to track periods
I did my trigger shot on 4/5-4/6 at midnight.   We had our ET of 2 embryos on Monday 4/10. I have my beta test this Friday, but yesterday and today, I broke down and tested. Both are FMU.   Do you think these are still the trigger shot or could I actually be pregnant? I'm not getting too excited, yet, and I have a few more tests so I'll retest again on Wednesday and Friday before my beta. Thoughts?
