Hi,doctor. My Tsh Level Is 100 After Delivery. Now I

Hi,doctor. My tsh level is 100 after delivery. Now I have gall bladder stone. Doctor advised to undergo surgery and increased 50mg of eltroxin to 150mg . Due to high tsh level surgery is delaying. And the tsh result is varying from one place to another. Do I want to take tablet and go for test or with empty stomach. If I can take table, how many hours before.
Can I feed my babies by taking tablet. Does it affect my twin baby.
