Uh?? Worried

Okay, so. I started my period. A week ago (Saturday the 14th) and it started as just brown discharge. Then light blood. No blood just discharge and blood clots. And every day up until Wednesday I only bled for one part of the day. Thursday it was a little heavier and so was Friday. But yesterday, (sat.21st) There was a loooot if blood clots way more than usual for me. Same today. Should I be worried?
