How early did you find out?

So I’m 10dpo and my period is supposed to start in 4 days. I took two tests today, one mid morning and one this evening and both were positive. This will be our third baby. I have never had a test positive this early. The last two times it wasn’t until the day before my missed period. I guess I’m just a little concerned because it’s so early and I used a first response which is known to detect super small amounts of hcg. How many dpo were you? Picture of the test today.
