Heavy bleeding

I’ve never such a heavy period before this cycle. I woke up with blood everywhere, my tampon didn’t last overnight, and normally it does. It sounds silly, but I don’t know how to handle it. My periods have always been kinda short and sweet. Like no more than 5 days, and moderate bleeding only for the first day or two and the rest very light. It’s so heavy now!!! Ugh. I’m constantly worried that I’ll be leaking everywhere now 😞
