Should I be worried? (Crazy heavy flow)

I use a menstral cup and so I can see and track my discharge better than most women. The past few months my flow has been “normal”. It’s been about 15ml. every 12 hours. This period it’s been 25ml. or more every 6 hours. I’m also having really large clots when I normal don’t. I’m talking over the size of a quarter.

Should I be worried or...?
