Heavy period and blood clots

Hi! I’m 22 and usually have a pretty steady flow. I don’t think I’ve had a period this heavy since I was a teenager. I use reusable/cloth pads and I’m soaking through them every few hours. Which has never happened. I’m also having pretty large clots. Sorry TMI. I’m not sure if i should be concerned or not. I’ve had more than a few today. They’re so big I can feel them coming out. I’m starting to freak myself out. Lol any advice will be helpful and appreciated!
