Am I or not cause wtf

Me and my bf we have a son already, and he’s 1 almost 2 and we’re trying for another baby. I took a test yesterday because my periods have been coming earlier than it says on glow, like literally 2 weeks 5 days with no period apart. But I thought I saw the tiniest faint line, but I very much so always hade line eyes. Is this enough sex for me to end up pregnant again? Is it possible that I could be and it’s a false negative?
