What’s the earliest dpo you could test positive for pregnancy?

My first pregnancy i really had no idea that i was pregnant so i took a test on 12/3 and I was already 5 weeks pregnant

My earliest was 8 dpo

My earliest was 8dpo as well but everyone is different. I used the test strips but all the other kinds of test didn’t show up for a couple days so it really depends on you and your body if it would show up that early

6dpo was the earliest with frer
