Tsh dosage for 9th week. Any other dose?

Hi doc, I am in my 9th week of pregnancy . I have subclinical hypothyroidism. My dosage was 100 mcg 4 days and 75mcg 3 days. At 5 weeks I checked my tsh and the levels were 8.145 . My diabetologist prescribed a increase in my dosage and it raised it to 100 mcg 5 days and 125 mcg 2 days . Recently after 4 weeks I checked my tsh again . The levels are 6.5. Now my diabetologist raised the dosage to 125 mcg everyday. I understand that tsh needs to be within 2.5 in first trimester. I'm already at 9 weeks and it's not controlled yet. As the increase in dosage is same as the previous increase amd since that dosage couldn't get my tsh levels down, I was wondering if my dosage must be increased more to 150 mcg or any other dose ? My only concern is to get it below 2.5 atleast in this 4 weeks. Please advice. Thank you ! My weight is 55kg and 167cm height
