Testing early question

So I'm curious. I got my first positive technically at 3w5d with a faint line using fourth pee and a no in digital. 3w6d I got a big ole thick line and a yes. To those that have tested early, did you have twins? My generation is supposed to be the ones to have twins so... I'm just curious 😂 I think it's absolutely crazy I'm testing this early. With my son I tested four days after my period was supposed to start. I was 9-8 days away when I got my positive. So crazy
