Normal or not

June and July my periods were so light and over a week late. I figured it was because I took plan B so it would take 2 months for my cycle to be regular so that would be this month I think... I have 2 period apps and one says my period is in 3 days and this one says 6 days but I just went pee and wiped and there was a little bit of blood. I thought my period would go back to normal like usually the first day its like a huge gush of blood. But its not a lot of blood right now?? i've taken 9 tests the past 2 months and theyve all been negative. Should I go get another test? Can someone tell me whats going on I'm freaking out right now idk what is happening
