BFN 4 days before expected period

Tested this morning with Canadian brand pregnancy tests that claim to detect as low as 10mil or whatever it’s measured by. Got another BFN this morning. Is there still hope? Should I try another brand or just wait it out? I’m antsy! My hubby and I have our 1st anniversary this Saturday and it would be day 2 of my period I am PRAYING hard that I can tell him he’s going to be a dad on our anniversary. We’ve been TTC for 5 months. Edit to add I used LH strips to confirm ovulation this month.
