Menstruation for 15 days

Hi guys, I just wanted advice to know how big of an emergency this is.

I’m severely fat. I was 235lbs for a 21 year old and I used to have severe period cramps so I visited my doctor last month. FYI I don’t get cramps when I don’t eat anything processed that month. We did ultrasounds and blood tests and everything came out fine.
No pcos, pcos, fibroids, maybe endometriosis but since my periods weren’t heavy/ only painful if I eat processed food we didn’t dig deep into it. I do have didelphus uterus (2 uteruses)

Now since then they put me up to weight loss and in 45 days I’ve lost around 15 pounds. And now I’ve been bleeding continuously for 15 days for this months period.

No cramps, no tiredness and the first 7-9 days it was little bleeding. It became medium for the next few days .And then I got tired of it and I took a OTC pill to pause bleeding but since then the bleeding has increased a lot like I have a full pad in 4-5 hours now. It’s been 3 days like this.

Idk what it is. I just want to know if it’s serious, if this is because of my weight loss or should I go to the doctor? I really am tired of bleeding. I want to stop. It feels like atleast when I was eating unhealthy I had regular periods which sounds so much better to me rn.

Please help
