Menorrhagia. Me what i should do now?

I've been taking trapic twice from the last four days with Limcee tablets. I am taking it on time, as the doctor suggested. Periods have not stopped till now; it started from the—14th of this month. Last month I got diagnosed with Hypothyroid, TSH value was 17.93. In a month, I dropped it to 7.53. Moreover, now the T3 value is 114, and T4  is 9.2. I am currently not taking any medicines for Hypothyroid. I exercise daily, sleeping satisfactorily, eating as the nutritionist said. I'm kind of on a keto diet. Apart from this, what can I do to stop this period? There are clots in periods of blood as well. Additionally, I was diagnosed with Pcod back then in 2017 too. Please suggest me what I should do now? My height is 155cms weight is 65.3kgs, and my age is 20.
