not sure what’s going on down there

So I’m 8 days late for my period . I’ve taken so many pregnancy tests , days before em period was supposed to start and during the week I should Of had it ... they all came back as negative. I don’t have any pregnancy symptoms compared to my last pregnancies. I’ve had creamy cm al week , and late at night I get period like cramps .

Today this came out and I’m not sure what to think. Iv always had regular periods but maybe it’s just extremely late for some reason? I don’t know . Currently still have cramping but not as much stuff coming out
