Period irregularities. Issue as of now.

I have been consukting doctors for my period issues for almost 11 years now but my period issues did not resolve. I am tired of consuming contraceptives to regularize my periods as dicontinuing them after the prescribed time the irregularities again come back. Also in 2024 I was diagnosed anemic due to heavy bleeding with Haemoglobin levels stooping down to 6 on the scale. When I get my periods big clots come out and once bleeding starts it doesn't stop. To stop it I again have to take trapic 650. I am obese now and I am trying to loose weight and take care of my diet as well but period issues still remain. Kindly suggest me a better way to get my periods on regular basis. Everytime I consult a gyneac they tell me to loose some weight you will get regular periods but if I loose weight the bleeding doesn't stop on its own when I get period. That's my issue as of now.
