Just found out I’m pregnant

So I have a question ladies. How long after your period was due that you got a positive? I took a 6 day sooner test like 3 days before my period was due and it was negative. Then after I was 2 days late I tested again and it was negative. After 4 days of being late I tested around 7:40pm just because, with a digital and it was positive. With my first baby I tested a few days before my period and got an instant positive so I guess I’m just confused
