when to take a test

i don’t get a period anymore because of my birth control pill. all pregnancy tests say “before your missed period” but uh, I don’t get one! so when am I supposed to take a pregnancy test?

(yes I am aware chances of me being pregnant on the pill are low, it is for peace of mind but I still want an accurate result from the test so I want to make sure I’m taking it at the right time)
