Please help! Period randomly got really heavy?

Normally my periods are pretty light. But I started a new diet I think a couple months ago (Keto diet). Ever since my period has been weird. At first it was like normal. But then over time my period kept coming late and getting a tiny bit heavier. It was still somewhat light/medium so I didn’t think anything of it. Then this month came, and I was 6 days late. Then finally hit my period. It was suddenly pretty heavy, and I kept clotting. My family and I have been cheating on the Keto diet recently cause of birthdays etc so idk if that why or what. But we don’t cheat really badly. This is my third day on my period and it’s really heavy. I got concerned when I woke up, and felt like I was peeing myself when I stood up. I could even sit on the toilet without blood literally dripping out of me. My pad was fully covered, and with my old periods my pads wouldn’t even be covered that much in a whole day. It’s only morning so idk if my period is going to get lighter through out the day. But I’m really concerned. Do you have any idea why my period is so heavy now, out of the blue? (Sorry Of most of this was tmi!)
